Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The vulnerability exists due to int32 overflow when insufficient validation of user-supplied input processed by the multiply_ms() function, as defined in the tools/ppm2tiff.c source code file. 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.
