Details

Irvan Kurniawan discovered that libwebp incorrectly handled certain memory
operations. If a user or automated system were tricked into opening a
specially crafted image file, a remote attacker could use this issue to
cause libwebp to crash, resulting in a denial of service, or possibly
execute arbitrary code.
