3 security issues in bullseye high

There are 3 open security issues in bullseye.

3 important issues:
  • CVE-2025-6021: A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
  • CVE-2025-49794: A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.
  • CVE-2025-49796: A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.

The VCS repository is not up to date, push the missing commits. high
vcswatch reports that the current version of the package is not in its VCS.
Either you need to push your commits and/or your tags, or the information about the package's VCS are out of date. A common cause of the latter issue when using the Git VCS is not specifying the correct branch when the packaging is not in the default one (remote HEAD branch), which is usually "master" but can be modified in salsa.debian.org in the project's general settings with the "Default Branch" field). Alternatively the Vcs-Git field in debian/control can contain a "-b <branch-name>" suffix to indicate what branch is used for the Debian packaging.

3 low-priority security issues in bookworm low

There are 3 open security issues in bookworm.

3 issues left for the package maintainer to handle:
  • CVE-2025-6021: (needs triaging) A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
  • CVE-2025-49794: (postponed; to be fixed through a stable update) A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.
  • CVE-2025-49796: (needs triaging) A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.

You can find information about how to handle these issues in the security team's documentation.
