Updated fail2ban packages fix CVE-2013-2178
Krzysztof Katowicz-Kowalewski discovered a vulnerability in Fail2ban, a log monitoring and system which can act on attack by preventing hosts to connect to specified services using the local firewall.
When using Fail2ban to monitor Apache logs, improper input validation in log parsing could enable a remote attacker to trigger an IP ban on arbitrary addresses, thus causing a denial of service (CVE-2013-2178).
