CVE-2006-2082: directory traversal / information leak in Quake III Arena auto download feature

Ludwig Nussel and Thilo Shulz discovered a vulnerability letting a malicious client download files from a server if auto download is enabled ( sv_allowDownload 1 ).

Issue #2 ( CVE pending ): R_RemapShaders buffer overflow

A second issue fixed in this release would let a malicious server exploit a buffer overflow to execute a shellcode on connecting clients.

Updated binaries for the following games are available:

Quake III Arena - fixed at version 1.32c
Return To Castle Wolfenstein - fixed at version 1.41b
Wolfenstein: Enemy Territory - fixed at version 2.60b

The zips hold binaries for all the operating systems we support. You need to upgrade to the latest through the usual installers first, and replace the engine binaries with the newer ones.

If you run a server with any older version, please upgrade or consider turning off autodownload ( set sv_allowDownload to 0 ). Wolfenstein: Enemy Territory servers http/ftp download feature is not affected by CVE-2006-2082. If you don't wish to upgrade, you can decide to only enable http/ftp downloads and disable legacy downloads in that particular case.

Finally, server administrators should note that game servers should be running in restricted environments as much as possible ( unpriviledged accounts and chroot jails ). It's a good thing to do the same for clients, or at least ensure that you are properly firewalled.
