Synopsis:	Moderate: pam security and bug fix update
Issue date:	2007-06-11
CVE Names:	CVE-2004-0813 CVE-2007-1716

A flaw was found in the way the Linux kernel handled certain SG_IO
commands. Console users with access to certain device files had the ability
to damage recordable CD drives. The way pam_console handled permissions of
these files has been modified to disallow access. This change also required
modifications to the cdrecord application. (CVE-2004-0813)

A flaw was found in the way pam_console set console device permissions. It
was possible for various console devices to retain ownership of the console
user after logging out, possibly leaking information to an unauthorized
user. (CVE-2007-1716)

The pam_unix module provides authentication against standard /etc/passwd
and /etc/shadow files. The pam_stack module provides support for stacking
PAM configuration files. Both of these modules contained small memory leaks
which caused problems in applications calling PAM authentication repeatedly
in the same process.
