Synopsis ========
Multiple vulnerabilities in UnrealIRCd might allow remote attackers to compromise the "unrealircd" account, or cause a Denial of Service.
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"
