Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists due to heap-based buffer overflow in the WriteTGAImage function of tga.c when processing malicious input. A remote attacker can cause the service to crash via a crafted image file, because the number of rows or columns can exceed the pixel-dimension restrictions of the TGA specification.
