Background ========== UnrealIRCd is an Internet Relay Chat (IRC) daemon. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/unrealircd < 3.2.8.1-r1 >= 3.2.8.1-r1 Description =========== Multiple vulnerabilities have been reported in UnrealIRCd: * The vendor reported a buffer overflow in the user authorization code. * The vendor reported that the distributed source code of UnrealIRCd was compromised and altered to include a system() call that could be called with arbitrary user input. Impact ====== A remote attacker could exploit these vulnerabilities to cause the execution of arbitrary commands with the privileges of the user running UnrealIRCd, or a Denial of Service condition. NOTE: By default UnrealIRCd on Gentoo is run with the privileges of the "unrealircd" user. Workaround ========== There is no known workaround at this time. Resolution ========== All UnrealIRCd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-irc/unrealircd-3.2.8.1-r1" References ========== [ 1 ] UnrealIRCd Security Advisory 20090413 http://www.unrealircd.com/txt/unrealsecadvisory.20090413.txt [ 2 ] UnrealIRCd Security Advisory 20100612 http://www.unrealircd.com/txt/unrealsecadvisory.20100612.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201006-21.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.
