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.
