Stack-based buffer overflow in the M_AddToServerList function in client/menu.c in Red Planet Arena Alien Arena 7.30 allows remote attackers to execute arbitrary code via a packet with a crafted server description to UDP port 27901 followed by a packet with a long print command.

Alien Arena 2007 6.10 and earlier allows remote attackers to cause a denial of service (client disconnect) by sending a client_connect command in a forged packet from the server to a client. NOTE: client IP addresses are available via product-specific queries.

Format string vulnerability in the safe_bprintf function in acesrc/acebot_cmds.c in Alien Arena 2007 6.10 and earlier allows remote attackers to cause a denial of service (daemon crash) via format string specifiers in a nickname.

Buffer overflow in the Quake 3 Engine, as used by (1) ET 2.60, (2) Return to Castle Wolfenstein 1.41, and (3) Quake III Arena 1.32b allows remote attackers to execute arbitrary commands via a long remapShader command.

The Com_sprintf function in q_shared.c in Alien Arena 2006 Gold Edition 5.00 does not properly NULL terminate certain long strings, which allows remote attackers (possibly authenticated) to cause a denial of service (application crash) via a long skin, weapon, or model name.

Stack-based buffer overflow in the Cmd_Say_f function in g_cmds.c in Alien Arena 2006 Gold Edition 5.00 allows remote attackers (possibly authenticated) to execute arbitrary code by sending a long message to the server.

Format string vulnerability in the safe_cprintf function in acebot_cmds.c in Alien Arena 2006 Gold Edition 5.00 allows remote attackers (possibly authenticated) to execute arbitrary code via unspecified vectors when the server sends crafted messages to the clients.

Quake 3 engine, as used in multiple games, allows remote attackers to cause a denial of service (client disconnect) via a long message, which is not properly truncated and causes the engine to process the remaining data as if it were network data.

The Unreal Engine, as used in DeusEx 1.112fm and earlier, Devastation 390 and earlier, Mobile Forces 20000 and earlier, Nerf Arena Blast 1.2 and earlier, Postal 2 1337 and earlier, Rune 107 and earlier, Tactical Ops 3.4.0 and earlier, Unreal 1 226f and earlier, Unreal II XMP 7710 and earlier, Unreal Tournament 451b and earlier, Unreal Tournament 2003 2225 and earlier, Unreal Tournament 2004 before 3236, Wheel of Time 333b and earlier, and X-com Enforcer, allows remote attackers to execute arbitrary code via a UDP packet containing a secure query with a long value, which overwrites memory.

Quake 3 arena 1.29f and 1.29g allows remote attackers to cause a denial of service (crash) via a malformed connection packet that begins with several char-255 characters.
