Severity: High
Title: Doomsday: Multiple vulnerabilities
Date: February 06, 2008
Bugs: #190835
ID: 200802-02
Synopsis
=======
Multiple vulnerabilities in Doomsday might allow remote execution of
arbitrary code or a Denial of Service.
Background
=========
The Doomsday Engine (deng) is a modern gaming engine for popular ID
games like Doom, Heretic and Hexen.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 games-fps/doomsday <= 1.9.0-beta5.2 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.
-------------------------------------------------------------------
-------------------------------------------------------------------
NOTE: Packages marked with asterisks require manual intervention!
==========
Luigi Auriemma discovered multiple buffer overflows in the
D_NetPlayerEvent() function, the Msg_Write() function and the
NetSv_ReadCommands() function. He also discovered errors when handling
chat messages that are not NULL-terminated (CVE-2007-4642) or contain a
short data length, triggering an integer underflow (CVE-2007-4643).
Furthermore a format string vulnerability was discovered in the
Cl_GetPackets() function when processing PSV_CONSOLE_TEXT messages
(CVE-2007-4644).
Impact
=====
A remote attacker could exploit these vulnerabilities to execute
arbitrary code with the rights of the user running the Doomsday server
or cause a Denial of Service by sending specially crafted messages to
the server.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
While some of these issues could be resolved in
"games-fps/doomsday-1.9.0-beta5.2", the format string vulnerability
(CVE-2007-4644) remains unfixed. We recommend that users unmerge
Doomsday:
# emerge --unmerge games-fps/doomsday
