Vulnerability details

The vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to heap-based buffer overflow in the gdkpixbufdec element when processing crafted image sequences with later frames larger than the first frame. A remote attacker can provide a specially crafted image sequence to execute arbitrary code.

The issue can also result in a crash, denial of service, or data corruption, and occurs because the output buffer pool is not re-evaluated when frame dimensions or pixel format change.
