 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-4402-1 [email protected] https://www.debian.org/lts/security/ Bastien Roucaris December 11, 2025 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : libsndfile Version : 1.0.31-2+deb11u2 CVE ID : CVE-2021-4156 Debian Bug : 1014713

 An out-of-bounds read flaw was found in libsndfile's FLAC codec functionality. An attacker who is able to submit a specially crafted file (via tricking a user to open or otherwise) to an application linked with libsndfile and using the FLAC codec, could trigger an out-of-bounds read that would most likely cause a crash but could potentially leak memory information that could be used in further exploitation of other flaws.

 For Debian 11 bullseye, this problem has been fixed in version 1.0.31-2+deb11u2.

 We recommend that you upgrade your libsndfile packages.

 For the detailed security status of libsndfile please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/libsndfile

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the libsndfile1 packages.
