Description

A flaw was found in GIMP. Processing a specially crafted PVR image file with large dimensions can lead to a denial of service (DoS). This occurs due to a stack-based buffer overflow and an out-of-bounds read in the PVR image loader, causing the application to crash. Systems that process untrusted PVR image files are affected.
