Vulnerability details
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to ReadRLEImage in coders/rle.c mishandles RLE headers that specify too few colors. A remote attacker can provide a specially crafted RLE document, trigger heap-based buffer over-read and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
