Title: Half-Life Counter-Strike Login Denial of Service Vulnerability
Severity: MODERATE
Description:
Half-Life Counter-Strike is a game distributed and maintained by Valve Software. It includes features that allow users to play locally or across a network. The game engine is used in many modifications.
The application is prone to a denial-of-service vulnerability because it fails to handle specially crafted network packets. The vulnerability occurs when logging in to the server. Specifically, this issue occurs when an attacker logs in to the affected application with malformed authentication credentials.
The attacker can exploit this issue by logging into the application twice with the same user-authentication credentials.
Successfully exploiting this issue will cause the affected application to crash, denying service to legitimate users.
This issue affects Half-Life Counter-Strike 1.6; other versions may also be affected.

- Valve Software Half-Life Counter-Strike 1.6
