Multiple vulnerabilities in Doomsday might allow remote execution of
arbitrary code or a Denial of Service.
The Doomsday Engine (deng) is a modern gaming engine for popular ID
games like Doom, Heretic and Hexen.
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
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
There is no known workaround at this time.
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
