The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in WritePNMImage in the coders/pnm.c file because of a misplaced "strncpy" and "an off-by-one" error. A remote attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
