========================================================================== Ubuntu Security Notice USN-2722-1 August 26, 2015
A security issue affects these releases of Ubuntu and its derivatives:
GDK-PixBuf could be made to crash or run programs as your login if it opened a specially crafted file.
Software Description: - gdk-pixbuf: GDK Pixbuf library
Gustavo Grieco discovered that GDK-PixBuf incorrectly handled scaling bitmap images. If a user or automated system were tricked into opening a BMP image file, a remote attacker could use this flaw to cause GDK-PixBuf to crash, resulting in a denial of service, or possibly execute arbitrary code.
The problem can be corrected by updating your system to the following package versions:
Ubuntu 15.04: libgdk-pixbuf2.0-0 2.31.3-1ubuntu0.1
Ubuntu 14.04 LTS: libgdk-pixbuf2.0-0 2.30.7-0ubuntu1.1
Ubuntu 12.04 LTS: libgdk-pixbuf2.0-0 2.26.1-1ubuntu1.2
After a standard system update you need to restart your session to make all the necessary changes.
