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.
