USN-216-1: GDK vulnerabilities

16 November 2005

gtk+2.0, gdk-pixbuf vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 5.10
  • Ubuntu 5.04
  • Ubuntu 4.10

Software Description

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)

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

Ubuntu 5.10
