USN-4013-1: libsndfile vulnerabilities

10 June 2019

Several security issues were fixed in libsndfile.



  • 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 18.10
Ubuntu 18.04
Ubuntu 16.04

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