Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to out-of-bounds read during insufficient validation of user-supplied input processed by the cpTags function, as defined in the tools/tiff2bw.c and tools/pal2rgb.c source code files. A remote unauthenticated attacker can trick the victim into opening or executing an image file that submits malicious input to the targeted system. A successful exploit could trigger memory corruption and cause the affected software to crash, resulting in a DoS condition.
