Severity:	high
Title:	bip: Multiple vulnerabilities
Date:	01/30/2012
Bugs:	#336321, #400599
ID:	201201-18

Synopsis

Multiple vulnerabilities in bip might allow remote unauthenticated attackers to cause a Denial of Service or possibly execute arbitrary code.

Background

bip is a multi-user IRC proxy with SSL support.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-irc/bip	< 0.8.8-r1	>= 0.8.8-r1	All supported architectures

Description

Multiple vulnerabilities have been discovered in bip:

Uli Schlachter reported that bip does not properly handle invalid data during authentication, resulting in a daemon crash (CVE-2010-3071).
Julien Tinnes reported that bip does not check the number of open file descriptors against FD_SETSIZE, resulting in a stack buffer overflow (CVE-2012-0806).

Impact

A remote attacker could exploit these vulnerabilities to execute arbitrary code with the privileges of the user running the bip daemon, or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All bip users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-irc/bip-0.8.8-r1"

NOTE: The CVE-2010-3071 flaw was already corrected in an earlier version of bip and is included in this advisory for completeness.
