Debian Security Advisory DSA-2979-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
July 17, 2014 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : fail2ban
CVE ID : CVE-2013-7176 CVE-2013-7177
Two vulnerabilities were discovered in Fail2ban, a solution to ban hosts
that cause multiple authentication errors. When using Fail2ban to monitor
Postfix or Cyrus IMAP logs, improper input validation in log parsing
could enable a remote attacker to trigger an IP ban on arbitrary
addresses, resulting in denial of service.
For the stable distribution (wheezy), these problems have been fixed in
version 0.8.6-3wheezy3.
For the testing distribution (jessie), these problems have been fixed in
version 0.8.11-1.
For the unstable distribution (sid), these problems have been fixed in
version 0.8.11-1.
We recommend that you upgrade your fail2ban packages.
