The vulnerability allows a remote attacker to cause DoS condition or execute arbitrary code on the target system.
The weakness exists due to input validation checking mechanisms in mew packet files. A remote attacker can send a specially crafted .pdf file, trigger a heap-based buffer over-read condition in mew.c and cause the service to crash or execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
