Description

If an administrator had specifically removed the default list of modules or failed to chose a module when operating debconf in a very unlikely non-default configuration, PAM would allow any authentication attempt, which could lead to remote attackers gaining access to a system with arbitrary privileges.

Attack Type: Authentication Management
