The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop within the ReadTXTImage in coders/txt.c, which allows attackers to cause a denial of service (CPU exhaustion) via a crafted image file that is mishandled in a GetImageIndexInList call. A remote attacker can consume all available system resources and trigger denial of service condition.
