Gentoo Linux Security Advisory

Title: UnrealIRCd: Multiple vulnerabilities (GLSA 201006-21)
Severity: high
Exploitable: remote
Date: June 14, 2010
Bug(s): #260806, #323691
ID: 201006-21

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: net-irc/unrealircd
Vulnerable: < 3.2.8.1-r1
Unaffected: >= 3.2.8.1-r1
Architectures: All supported architectures


Description


Multiple vulnerabilities have been reported in UnrealIRCd:
  • The vendor reported a buffer overflow in the user authorization
    code (CVE-2009-4893).
  • 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 (CVE-2010-2075).


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-irc/unrealircd-3.2.8.1-r1"
