CVE-2009-0362

Publication date 13 February 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

filter.d/wuftpd.conf in Fail2ban 0.8.3 uses an incorrect regular expression that allows remote attackers to cause a denial of service (forced authentication failures) via a crafted reverse-resolved DNS name (rhost) entry that contains a substring that is interpreted as an IP address, a different vulnerability than CVE-2007-4321.
