Debian DSA-2979-1 : fail2ban - security update

medium Nessus Plugin ID 76583

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the fail2ban packages.

For the stable distribution (wheezy), these problems have been fixed in version 0.8.6-3wheezy3.
