USN-216-1: GDK vulnerabilities

Releases

• Ubuntu 5.10
• Ubuntu 5.04
• Ubuntu 4.10

Details

Two integer overflows have been discovered in the XPM image loader of
the GDK pixbuf library. By tricking an user into opening a specially
crafted XPM image with any Gnome desktop application that uses this
library, this could be exploited to execute arbitrary code with the
privileges of the user running the application.
(CVE-2005-2976, CVE-2005-3186)

Additionally, specially crafted XPM images could cause an endless loop
in the image loader, which could be exploited to cause applications
trying to open that image to hang. (CVE-2005-2975)

Update instructions

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

Ubuntu 5.10

• libgdk-pixbuf2 -
• gtk2-engines-pixbuf -

Ubuntu 5.04

• libgdk-pixbuf2 -
• gtk2-engines-pixbuf -

Ubuntu 4.10

• gtk2-engines-pixbuf -

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