Ubuntu 8.10 / 9.04 : pam vulnerability (USN-828-1)
high Nessus Plugin ID 40906
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Russell Senior discovered that the system authentication module selection mechanism for PAM did not safely handle an empty selection.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. This did not affect default Ubuntu installations.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
