<p>This page lists all security vulnerabilities fixed in
released versions of Apache Commons Compress. Each
vulnerability is given a security impact rating by the
development team - please note that this rating may vary from
platform to platform. We also list the versions of Commons
Compress the flaw is known to affect, and where a flaw has not
been verified list the version with a question mark.</p>
<p>Please note that binary patches are never provided. If you
need to apply a source code patch, use the building
instructions for the Commons Compress version that you are
using.</p>

<p><b>Important: Denial of Service</b> <a
href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-25710">CVE-2024-25710</a></p>
<p>This affects version 1.3 through 1.25.0.</p>
<p>This denial of service is caused by an infinite loop reading a corrupted DUMP file.</p>
<p>Users are recommended to upgrade to version 1.26.0 which fixes the issue.</p>

<p><b>Moderate: Denial of Service</b> <a
href="https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2023-42503">CVE-2023-42503</a></p>
<p>Improper Input Validation, Uncontrolled Resource Consumption vulnerability in Apache Commons Compress in TAR parsing.</p>
<p>This issue affects Apache Commons Compress: from 1.22 before 1.24.0.</p>
<p>Users are recommended to upgrade to version 1.24.0, which fixes the issue.</p>
<p>A third party can create a malformed TAR file by manipulating file modification times headers,
which when parsed with Apache Commons Compress, will cause a denial of service issue via CPU consumption.</p>
<p>In version 1.22 of Apache Commons Compress, support was added for file modification times with higher precision
(issue # COMPRESS-612<sup><a href="#Ref-1-24-1">[1]</a></sup>).
The format for the PAX extended headers carrying this data consists of two numbers separated by a period<sup><a href="#Ref-1-24-2">[2]</a></sup>,
indicating seconds and subsecond precision (for example “1647221103.5998539”). The impacted fields are “atime”, “ctime”, “mtime” and
“LIBARCHIVE.creationtime”. No input validation is performed prior to the parsing of header values.</p>
<p>Parsing of these numbers uses the BigDecimal<sup><a href="#Ref-1-24-3">[3]</a></sup> class from the JDK which has a publicly known algorithmic complexity issue when doing
operations on large numbers, causing denial of service (see issue # JDK-6560193<sup><a href="#Ref-1-24-4">[4]</a></sup>). A third party can manipulate file time headers
in a TAR file by placing a number with a very long fraction (300,000 digits) or a number with exponent notation (such as “9e9999999”)
within a file modification time header, and the parsing of files with these headers will take hours instead of seconds, leading to a
denial of service via exhaustion of CPU resources. This issue is similar to CVE-2012-2098<sup><a href="#Ref-1-24-5">[5]</a></sup>.</p>

</ul>
<p>Only applications using CompressorStreamFactory class (with auto-detection of file types), TarArchiveInputStream and TarFile
classes to parse TAR files are impacted. Since this code was introduced in v1.22, only that version and later versions are impacted.</p>
