CVE-2009-0579

Publication date 16 April 2009

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Linux-PAM before 1.0.4 does not enforce the minimum password age (MINDAYS) as specified in /etc/shadow, which allows local users to bypass intended security policy and change their passwords sooner than specified.
