USN-5528-1: FreeType vulnerabilities

20 July 2022

Several security issues were fixed in FreeType.



  • freetype - FreeType 2 is a font engine library


It was discovered that FreeType did not correctly handle certain malformed
font files. If a user were tricked into using a specially crafted font
file, a remote attacker could cause FreeType to crash, or possibly execute
arbitrary code.

Update instructions

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

Ubuntu 22.04
Ubuntu 20.04
Ubuntu 18.04

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