Title: BZFlag Reconnect Denial Of Service Vulnerability

Severity: MODERATE

Description:

BZFlag is a multi-player action game. It is available for a number of operating systems, including Microsoft Windows and Unix/Linux variants.

BZFlag is prone to a denial of service vulnerability. Users that have established a session with BZFlag may cause a denial of service by reconnecting and flooding BZFlag ports with excessive amounts of data. This may reportedly cause a server crash or a memory leak that could exhaust available resources. Though unconfirmed, exploitation could result in memory corruption, which may allow for execution of malicious code.

This issue was reported in BZFlag 1.7g0. Other versions are also likely affected.

Affected Products:

  • BZFlag BZFlag 1.7.0g0
