Synopsis
Multiple vulnerabilities in bip might allow remote unauthenticated
attackers to cause a Denial of Service or possibly execute arbitrary code.
2.
Impact Information
Background
bip is a multi-user IRC proxy with SSL support.
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.

Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All bip users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# 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.
