|Gentoo Linux Security Advisory
Title: bip: Multiple vulnerabilities (GLSA 201201-18)
Date: January 30, 2012
Bug(s): #336321, #400599
Multiple vulnerabilities in bip might allow remote unauthenticated
attackers to cause a Denial of Service or possibly execute arbitrary code.
bip is a multi-user IRC proxy with SSL support.
Vulnerable: < 0.8.8-r1
Unaffected: >= 0.8.8-r1
Architectures: All supported architectures
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
- Julien Tinnes reported that bip does not check the number of open
file descriptors against FD_SETSIZE, resulting in a stack buffer
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.
There is no known workaround at this time.
All bip users should upgrade to the latest version:
NOTE: The CVE-2010-3071 flaw was already corrected in an earlier version
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-irc/bip-0.8.8-r1"
of bip and is included in this advisory for completeness.
