Gus! & Psilord freesweep Environment Variable Local Overflow
Local Access Required Input Manipulation
Loss of Integrity

- 漏洞描述

A local overflow exists in Gus! & Psilord freesweep. Freesweep fails to correctly check the length of environment variables resulting in a buffer overflow. With a specially crafted request, an attacker can cause arbitrary code to be executed at the game group privilege level resulting in a loss of integrity.
