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! Description =========== 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 References ========== [ 1 ] CVE-2007-4642 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4642 [ 2 ] CVE-2007-4643 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4643 [ 3 ] CVE-2007-4644 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-4644 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200802-02.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
