CVE-2018-19840
CWE-835
The function WavpackPackInit in pack_utils.c in libwavpack.a in WavPack through 5.1.0 allows attackers to cause a denial-of-service (resource exhaustion caused by an infinite loop) via a crafted wav audio file because WavpackSetConfiguration64 mishandles a sample rate of zero.

CVE-2015-7799
null
The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel through 4.2.3 does not ensure that certain slot numbers are valid, which allows local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/slip/slhc.c?id=4ab42d78e37a294ac7bc56901d563c642e03c4ae
ppp, slip: Validate VJ compression slot parameters completely Currently slhc_init() treats out-of-range values of rslots and tslots as equivalent to 0, except that if tslots is too large it will dereference a null pointer (CVE-2015-7799). Add a range-check at the top of the function and make it return an ERR_PTR() on error instead of NULL. Change the callers accordingly. Compile-tested only.

Xilmi ai (#45) * Replaced many isPlayer() by isPlayerControlled() This leads to a more fluent experience on AutoPlay. Note: the council-voting acts weird when you try that there, getting you stuck, and the News-Broadcasts also seem to use a differnt logic and are always shown. * Orion-guard-handling Avoid sending colonization-fleets, when guardian is still alive Increase guardian-power-estimate to 100,000 Don't send and count bombers towards guardian-defeat-force * Fixed Crash from a report on reddit Not sure how that could happen though. Never had this issue in games started on my computer. * Fixed crash after AI defeats orion-guard Tried to access an out-of-bounds-value because it couldn't find the System where the guardian was. So looking to find the Planet with the Orionartifact now, which does find it. * All the forgotten isPlayer()-calls Including the Base- and Modnar-AI-Diplomat * Personalities now play a role in my AI once again Instead of everyone having the same conditions for war, there's now different ones. Some are more aggressive, some are less. * Fixed issue where enemy-fleets weren's seen, when they actually were. Also added a way of guessing when enemy-fleets aren't seen so it shouldn't trickle in tiny fleets that all retreat anymore in the early-game, before they can see the enemy-fleets. And also not later because they now actually can see them. * Update AIDiplomat.java * Delete ShipCombatResults.java * Delete Empire.java * Delete TradeRoute.java * Revert "Delete TradeRoute.java" This reverts commit 6e5c5a8604e89bb11a9a6dc63acd5b3f27194c83. * Revert "Delete Empire.java" This reverts commit 1a020295e05ebc735dae761f426742eb7bdc8d35. * Revert "Delete ShipCombatResults.java" This reverts commit 5f9287289feb666adf1aa809524973c54fbf0cd5. * Update ShipCombatResults.java reverting pull-request... manually because I don't know of a better way 8[ * Update Empire.java * Update TradeRoute.java * Merge with Master * Update TradeRoute.java * Update TradeRoute.java github editor does not allow me to remove a newline oO * AI improvements Added parameter to make the colonizer-function return just the uncolonized planets without substracting the colony-ships. Impelemented a very differnt diplomatic behavior, that supposedly is more suitable to actually winning by waging less war, particularly when big enough to be voted for. Revoked that AI doesn't adjust to enemy-troops when it has a more defensive unit-composition. In lategame going by destructive-power of bombers hasn't much merit, when 1 bombers can pack 60ish neutronium-bombs. Fixed an issue that prevented designing extended-fuel-range-colonizers asap. This once again helps expansion-speed a lot. Security now is only spent against empires actually in range to spy, as it was intended. Contact via council should not increase paranoia. Also Xenophobic-extra-paranoia removed. * Update OrionGuardianShip.java Co-authored-by: rayfowler <58891984+rayfowler@users.noreply.github.com>

https://github.com/qpdf/qpdf/commit/d71f05ca07eb5c7cfa4d6d23e5c1f2a800f52e8e
Fix sign and conversion warnings (major) This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.

CWE-917,CWE-20
GeoTools is an open source Java library that provides tools for geospatial data. The GeoTools library has a number of data sources that can perform unchecked JNDI lookups, which in turn can be used to perform class deserialization and result in arbitrary code execution. Similar to the Log4J case, the vulnerability can be triggered if the JNDI names are user-provided, but requires admin-level login to be triggered. The lookups are now restricted in GeoTools 26.4, GeoTools 25.6, and GeoTools 24.6. Users unable to upgrade should ensure that any downstream application should not allow usage of remotely provided JNDI strings.

CVE-2022-23589
CWE-476
Tensorflow is an Open Source Machine Learning Framework. Under certain scenarios, Grappler component of TensorFlow can trigger a null pointer dereference. There are 2 places where this can occur, for the same malicious alteration of a `SavedModel` file (fixing the first one would trigger the same dereference in the second place). First, during constant folding, the `GraphDef` might not have the required nodes for the binary operation. If a node is missing, the correposning `mul_*child` would be null, and the dereference in the subsequent line would be incorrect. We have a similar issue during `IsIdentityConsumingSwitch`. The fix will be included in TensorFlow 2.8.0. We will also cherrypick this commit on TensorFlow 2.7.1, TensorFlow 2.6.3, and TensorFlow 2.5.3, as these are also affected and still in supported range.

In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices for the tensors, indexing into an array of tensors that is owned by the subgraph. This results in a pattern of double array indexing when trying to get the data of each tensor. However, some operators can have some tensors be optional. To handle this scenario, the flatbuffer model uses a negative `-1` value as index for these tensors. This results in special casing during validation at model loading time. Unfortunately, this means that the `-1` index is a valid tensor index for any operator, including those that don't expect optional inputs and including for output tensors. Thus, this allows writing and reading from outside the bounds of heap allocated arrays, although only at a specific offset from the start of these arrays. This results in both read and write gadgets, albeit very limited in scope. The issue is patched in several commits (46d5b0852, 00302787b7, e11f5558, cd31fd0ce, 1970c21, and fff2c83), and is released in TensorFlow versions 1.15.4, 2.0.3, 2.1.2, 2.2.1, or 2.3.1. A potential workaround would be to add a custom `Verifier` to the model loading code to ensure that only operators which accept optional inputs use the `-1` special value and only for the tensors that they expect to be optional. Since this allow-list type approach is erro-prone, we advise upgrading to the patched code.

[tflite]: Insert `nullptr` checks when obtaining tensors. As part of ongoing refactoring, `tflite::GetInput`, `tflite::GetOutput`, `tflite::GetTemporary` and `tflite::GetIntermediates` will return `nullptr` in some cases. Hence, we insert the `nullptr` checks on all usages. We also insert `nullptr` checks on usages of `tflite::GetVariableInput` and `tflite::GetOptionalInputTensor` but only in the cases where there is no obvious check that `nullptr` is acceptable (that is, we only insert the check for the output of these two functions if the tensor is accessed as if it is always not `nullptr`).

CVE-2021-4001
CWE-367
A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. This flaw affects kernel versions prior to 5.16 rc2.
https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf.git/commit/?id=353050be4c19e102178ccc05988101887c25ae53
bpf: Fix toctou on read-only map's constant scalar tracking Commit a23740ec43ba ("bpf: Track contents of read-only maps as scalars") is checking whether maps are read-only both from BPF program side and user space side, and then, given their content is constant, reading out their data via map->ops->map_direct_value_addr() which is then subsequently used as known scalar value for the register, that is, it is marked as __mark_reg_known() with the read value at verification time. Before a23740ec43ba, the register content was marked as an unknown scalar so the verifier could not make any assumptions about the map content. The current implementation however is prone to a TOCTOU race, meaning, the value read as known scalar for the register is not guaranteed to be exactly the same at a later point when the program is executed, and as such, the prior made assumptions of the verifier with regards to the program will be invalid which can cause issues such as OOB access, etc. While the BPF_F_RDONLY_PROG map flag is always fixed and required to be specified at map creation time, the map->frozen property is initially set to false for the map given the map value needs to be populated, e.g. for global data sections. Once complete, the loader "freezes" the map from user space such that no subsequent updates/deletes are possible anymore. For the rest of the lifetime of the map, this freeze one-time trigger cannot be undone anymore after a successful BPF_MAP_FREEZE cmd return. Meaning, any new BPF_* cmd calls which would update/delete map entries will be rejected with -EPERM since map_get_sys_perms() removes the FMODE_CAN_WRITE permission. This also means that pending update/delete map entries must still complete before this guarantee is given. This corner case is not an issue for loaders since they create and prepare such program private map in successive steps. However, a malicious user is able to trigger this TOCTOU race in two different ways: i) via userfaultfd, and ii) via batched updates. For i) userfaultfd is used to expand the competition interval, so that map_update_elem() can modify the contents of the map after map_freeze() and bpf_prog_load() were executed. This works, because userfaultfd halts the parallel thread which triggered a map_update_elem() at the time where we copy key/value from the user buffer and this already passed the FMODE_CAN_WRITE capability test given at that time the map was not "frozen". Then, the main thread performs the map_freeze() and bpf_prog_load(), and once that had completed successfully, the other thread is woken up to complete the pending map_update_elem() which then changes the map content. For ii) the idea of the batched update is similar, meaning, when there are a large number of updates to be processed, it can increase the competition interval between the two. It is therefore possible in practice to modify the contents of the map after executing map_freeze() and bpf_prog_load(). One way to fix both i) and ii) at the same time is to expand the use of the map's map->writecnt. The latter was introduced in fc9702273e2e ("bpf: Add mmap() support for BPF_MAP_TYPE_ARRAY") and further refined in 1f6cb19be2e2 ("bpf: Prevent re-mmap()'ing BPF map as writable for initially r/o mapping") with the rationale to make a writable mmap()'ing of a map mutually exclusive with read-only freezing. The counter indicates writable mmap() mappings and then prevents/fails the freeze operation. Its semantics can be expanded beyond just mmap() by generally indicating ongoing write phases. This would essentially span any parallel regular and batched flavor of update/delete operation and then also have map_freeze() fail with -EBUSY. For the check_mem_access() in the verifier we expand upon the bpf_map_is_rdonly() check ensuring that all last pending writes have completed via bpf_map_write_active() test. Once the map->frozen is set and bpf_map_write_active() indicates a map->writecnt of 0 only then we are really guaranteed to use the map's data as known constants. For map->frozen being set and pending writes in process of still being completed we fall back to marking that register as unknown scalar so we don't end up making assumptions about it. With this, both TOCTOU reproducers from i) and ii) are fixed. Note that the map->writecnt has been converted into a atomic64 in the fix in order to avoid a double freeze_mutex mutex_{un,}lock() pair when updating map->writecnt in the various map update/delete BPF_* cmd flavors. Spanning the freeze_mutex over entire map update/delete operations in syscall side would not be possible due to then causing everything to be serialized. Similarly, something like synchronize_rcu() after setting map->frozen to wait for update/deletes to complete is not possible either since it would also have to span the user copy which can sleep. On the libbpf side, this won't break d66562fba1ce ("libbpf: Add BPF object skeleton support") as the anonymous mmap()-ed "map initialization image" is remapped as a BPF map-backed mmap()-ed memory where for .rodata it's non-writable.

CVE-2021-3443
CWE-476
A NULL pointer dereference flaw was found in the way Jasper versions before 2.0.27 handled component references in the JP2 image format decoder. A specially crafted JP2 image file could cause an application using the Jasper library to crash when opened.
https://github.com/jasper-software/jasper/commit/f94e7499a8b1471a4905c4f9c9e12e60fe88264b
Fixes #269. Added a check for an invalid component reference in the JP2 decoder. Added a related test case for the JP2 codec.

ipv6: add complete rcu protection around np->opt This patch addresses multiple problems : UDP/RAW sendmsg() need to get a stable struct ipv6_txoptions while socket is not locked : Other threads can change np->opt concurrently. Dmitry posted a syzkaller (http://github.com/google/syzkaller) program desmonstrating use-after-free. Starting with TCP/DCCP lockless listeners, tcp_v6_syn_recv_sock() and dccp_v6_request_recv_sock() also need to use RCU protection to dereference np->opt once (before calling ipv6_dup_options()) This patch adds full RCU protection to np->opt Reported-by: Dmitry Vyukov <dvyukov@google.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Hannes Frederic Sowa <hannes@stressinduktion.org> Signed-off-by: David S.

nbd-client: Fix regression when server sends garbage When we switched NBD to use coroutines for qemu 2.9 (in particular, commit a12a712a), we introduced a regression: if a server sends us garbage (such as a corrupted magic number), we quit the read loop but do not stop sending further queued commands, resulting in the client hanging when it never reads the response to those additional commands. In qemu 2.8, we properly detected that the server is no longer reliable, and cancelled all existing pending commands with EIO, then tore down the socket so that all further command attempts get EPIPE. Restore the proper behavior of quitting (almost) all communication with a broken server: Once we know we are out of sync or otherwise can't trust the server, we must assume that any further incoming data is unreliable and therefore end all pending commands with EIO, and quit trying to send any further commands. As an exception, we still (try to) send NBD_CMD_DISC to let the server know we are going away (in part, because it is easier to do that than to further refactor nbd_teardown_connection, and in part because it is the only command where we do not have to wait for a reply). Based on a patch by Vladimir Sementsov-Ogievskiy. A malicious server can be created with the following hack, followed by setting NBD_SERVER_DEBUG to a non-zero value in the environment when running qemu-nbd: | --- a/nbd/server.c | +++ b/nbd/server.c | @@ -919,6 +919,17 @@ static int nbd_send_reply(QIOChannel *ioc, NBDReply *reply, Error **errp) | stl_be_p(buf + 4, reply->error) | stq_be_p(buf + 8, reply->handle) | | + static int debug | + static int count | + if (!count++) { | + const char *str = getenv("NBD_SERVER_DEBUG") | + if (str) { | + debug = atoi(str) | + } | + } | + if (debug && !(count % debug)) { | + buf[0] = 0 | + } | return nbd_write(ioc, buf, sizeof(buf), errp) | } Reported-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Signed-off-by: Eric Blake <eblake@redhat.com> Message-Id: <20170814213426.24681-1-eblake@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com>

Fix leaks in kadmin server stubs [CVE-2015-8631] In each kadmind server stub, initialize the client_name and server_name variables, and release them in the cleanup handler. Many of the stubs will otherwise leak the client and server name if krb5_unparse_name() fails. Also make sure to free the prime_arg variables in rename_principal_2_svc(), or we can leak the first one if unparsing the second one fails. Discovered by Simo Sorce. CVE-2015-8631: In all versions of MIT krb5, an authenticated attacker can cause kadmind to leak memory by supplying a null principal name in a request which uses one. Repeating these requests will eventually cause kadmind to exhaust all available memory.

Dataset Card for TitanVul

TitanVul is a large-scale function-level vulnerability dataset constructed for training machine learning models for vulnerability detection. It consists of paired vulnerability-fix function samples aggregated from multiple public sources and validated using a multi-agent LLM framework.

Dataset Details

TitanVul is designed to provide high-quality training data that generalizes across vulnerability types and codebases. The dataset is built by aggregating seven public vulnerability datasets, followed by extensive deduplication and multi-agent LLM-based validation to reduce noise and improve label reliability.

  • Curated by: Yikun Li, Ngoc Tan Bui, Ting Zhang, Martin Weyssow, Chengran Yang, Xin Zhou, Jinfeng Jiang, Junkai Chen, Huihui Huang, Huu Hung Nguyen, Chiok Yew Ho, Jie Tan, Ruiyin Li, Yide Yin, Han Wei Ang, Frank Liauw, Eng Lieh Ouh, Lwin Khin Shar, David Lo
  • Language(s): Source code (multilingual).
  • Paper: arXiv:2507.21817 (Out of Distribution, Out of Luck: How Well Can LLMs Trained on Vulnerability Datasets Detect Top 25 CWE Weaknesses?)

Dataset Structure

TitanVul is released as a CSV archive containing function-level vulnerability-fix pairs:

  • Each sample represents a vulnerable function and its corresponding fixed version.
  • The dataset includes metadata aggregated from multiple public sources.
  • Deduplication is applied to reduce overlap across merged datasets.

The released version contains 38,548 vulnerability-fix function pairs.
