| # Third-party provenance and notices | |
| ## Source heap-operation sequences | |
| The 40 initial sequences were captured from ExploitGym heap-vulnerability samples spanning 28 upstream projects. `data/sample_sources.csv` records the project name and upstream sample entry for each source. The release includes generated task specimens and source annotations; upstream vulnerable project source trees and their original vulnerability-triggering inputs are not included. | |
| The upstream ExploitGym checkout distinguishes its Apache-2.0 source-code license from the individual licenses of its task data. Its notices are preserved in `licenses/ExploitGym-DATA_LICENSE.md` and `licenses/ExploitGym-Apache-2.0.txt` for provenance. The Apache-2.0 notice does not confer a blanket license on all upstream task data. The CC BY 4.0 license on this dataset likewise grants no additional rights in upstream materials. | |
| For the user-space CyberGym/ARVO/OSS-Fuzz samples, upstream materials retain the terms of the corresponding projects. Source references: | |
| - CyberGym: https://github.com/sunblaze-ucb/cybergym | |
| - ARVO: https://github.com/n132/ARVO | |
| - OSS-Fuzz: https://github.com/google/oss-fuzz | |
| ## Allocator references | |
| The task metadata and ELF specimens refer to glibc ptmalloc 2.23/2.35, jemalloc 5.3.1, and musl mallocng 1.2.6. Their source trees and shared allocator libraries are not included in this data repository. Those projects retain their own licenses and copyright notices: | |
| - glibc: https://www.gnu.org/software/libc/ | |
| - jemalloc: https://github.com/jemalloc/jemalloc/blob/5.3.1/COPYING | |
| - musl: https://git.musl-libc.org/cgit/musl/tree/COPYRIGHT?h=v1.2.6 | |
| Mention of a project identifies data origin or the recorded task configuration and does not imply endorsement by that project. | |
