GLSA-200802-02 : Doomsday: Multiple vulnerabilities

critical Nessus Plugin ID 30244

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200802-02 (Doomsday: Multiple vulnerabilities)

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.

Solution

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
