Name of the Vulnerable Software and Affected Versions gdk-pixbuf versions prior to 2.42.0

Description A flaw in gdk-pixbuf can cause an integer wraparound leading to an out of bounds write when a crafted GIF image is loaded. This may allow an attacker to crash applications or potentially execute code on the victim system, posing a threat to data confidentiality and integrity as well as system availability.

Recommendations For versions prior to 2.42.0, update to version 2.42.0 or later to resolve the issue. As a temporary workaround, consider avoiding the use of crafted GIF images until a patch is applied. Restrict access to sensitive data and systems to minimize the risk of exploitation.
