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
-------------------------------------------------------------------
1 net-irc/bip < 0.8.8-r1 >= 0.8.8-r1
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.
