  • libpng - PNG (Portable Network Graphics) file library

Details

It was discovered that libpng incorrectly handled certain memory
operations. If a user or automated system using libpng were tricked into
opening a specially crafted image, an attacker could exploit this to cause
a denial of service or execute code with the privileges of the user
invoking the program.

Update instructions

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

Ubuntu 8.04
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.10
Ubuntu 10.04

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