USN-5409-1: libsndfile vulnerability

10 May 2022

libsndfile could be made to crash or expose sensitive information if it received specially crafted input.



  • libsndfile - Library for reading/writing audio files


It was discovered that libsndfile was incorrectly performing memory
management operations and incorrectly using buffers when executing
its FLAC codec. If a user or automated system were tricked into
processing a specially crafted sound file, an attacker could
possibly use this issue to cause a denial of service or obtain
sensitive information.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
