Description


Jason Geffner has reported a vulnerability in Alien Arena, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the "M_AddToServerList()" function in client/menu.c. This can be exploited to cause a stack-based buffer overflow via a specially crafted UDP packet sent to port 27901.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in version 7.30. Prior versions may also be affected.


Solution:
Update to version 7.31 or later.
