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

The weakness exists due to stack-based buffer overflow. A remote attacker can insert a specially crafted cookie into a GET request, trigger memory corruption and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Update to version 1.34 or later.
