Details follow: 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)
