Synopsis ========
Multiple vulnerabilities have been found in Fail2ban, the worst of which allows remote attackers to cause a Denial of Service condition.
Background ==========
Fail2ban is a tool for parsing log files and banning IP addresses which show suspicious behavior.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/fail2ban < 0.8.12 >= 0.8.12
Description ===========
Multiple vulnerabilities have been discovered in Fail2ban. Please review the CVE identifiers referenced below for details.
Impact ======
A remote attacker could send a crafted URL to a web site which, when parsed by Fail2ban, would deny a specific IP address. Also, errors in regular expressions within certain filters can cause arbitrary IP addresses to be banned. Furthermore, a local attacker could perform symlink attacks to overwrite arbitrary files with the privileges of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Fail2ban users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-analyzer/fail2ban-0.8.12
