The vulnerability allows a remote attacker to cause a denial of service.

The vulnerability exists due to integer overflow in the despeckle operation when processing crafted input on 32-bit builds. A remote attacker can trigger an out-of-bounds write to cause a denial of service.

Only 32-bit builds are vulnerable.
