USN-4593-1: FreeType vulnerability

20 October 2020

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



  • freetype - FreeType 2 is a font engine library


Sergei Glazunov 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 with user privileges.

Update instructions

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

Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04

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