Quake 3 engine CL_ParseDownload() buffer overflow
| quake3-clparsedownload-bo (26889) |  High Risk |
Description:
Multiple game servers based on the Quake 3 engine are vulnerable to a buffer overflow in the CL_ParseDownload() function in code/client/cl_parse.c. By sending a specially-crafted svc_download command, a remote attacker in control of a malicious game server could overflow a buffer and execute arbitrary code on a Quake 3 client system, if the attacker could persuade a potential victim to connect to the malicious server.
Consequences:
Gain Access
Remedy:
No remedy available as of November 2008.

- CVE-2006-2875: Stack-based buffer overflow in the CL_ParseDownload function of Quake 3 Engine 1.32c and earlier, as used in multiple products, allows remote attackers to execute arbitrary code via a svc_download command with compressed data that triggers the overflow during expansion.
- CVE-2006-3325: client/cl_parse.c in the id3 Quake 3 Engine 1.32c and the Icculus Quake 3 Engine (ioquake3) revision 810 and earlier allows remote malicious servers to overwrite arbitrary write-protected cvars variables on the client, such as cl_allowdownload for Automatic Downloading and fs_homepath for the quake3 path, via a string of cvar names and values sent from the server. NOTE: this can be combined with another vulnerability to overwrite arbitrary files.
