USN-5025-1: libsndfile vulnerability

29 July 2021

libsndfile could be made to crash or run programs as your login if it opened a specially crafted file.



  • libsndfile - Library for reading/writing audio files


It was discovered that libsndfile incorrectly handled certain malformed
files. A remote attacker could use this issue to cause libsndfile to crash,
resulting in a denial of service, or possibly execute arbitrary code.

Update instructions

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

Ubuntu 21.04
Ubuntu 20.04
Ubuntu 18.04

After a standard system update you need to restart your session to make
all the necessary changes.
