Title: Quake 3 Arena Possible Buffer Overflow Vulnerability
Severity: HIGH
Description:
Quake 3 Arena Server is a software package designed to host multiple Quake 3 players over a network for interactive play.
A vulnerability exists in this software that can allow a malicious user to remotely crash a Quake 3 Server. Execution of arbitrary code may be possible as well.
The presence of any characters following the 'connect' message in a datagram recieved by Quake 3 Arena server will cause it to crash. This behaviour is indicative of a buffer overflow and may allow for the execution of arbitrary code.
If execution of shellcode is possible, remote attackers may be able to gain access to hosts running the server. At the very least, this vulnerability can be used to cause a denial of service.

- id Software Quake 3 Arena Server 1.29.0 f
