USN-4156-2: SDL vulnerabilities

16 October 2019

Several security issues were fixed in SDL.



  • libsdl1.2 - Simple DirectMedia Layer debug files


USN-4156-1 fixed several vulnerabilities in SDL. This update provides
the corresponding update for Ubuntu 12.04 ESM and Ubuntu 14.04 ESM.

Original advisory details:

It was discovered that SDL incorrectly handled certain images. If a user
were tricked into opening a crafted image file, a remote attacker could
use this issue to cause SDL to crash, resulting in a denial of service, or
possibly execute arbitary code.

Update instructions

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

Ubuntu 14.04
Ubuntu 12.04

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