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

<p>bip is a multi-user IRC proxy with SSL support.</p>
<p>Multiple vulnerabilities have been discovered in bip:</p>
<li>Uli Schlachter reported that bip does not properly handle invalid
data during authentication, resulting in a daemon crash
<li>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 type="high">
<p>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.
<p>There is no known workaround at this time.</p>
<p>All bip users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-irc/bip-0.8.8-r1"
<p>NOTE: The CVE-2010-3071 flaw was already corrected in an earlier version
of bip and is included in this advisory for completeness.
