Description

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.

Remediation

Update to version 0.99.3.
