Name        : pam
Versions    : rh7.3: pam-0.75-46.10.legacy
Versions    : rh9: pam-0.75-62.10.legacy
Summary     : A security tool which provides authentication for
               applications.
Description :
PAM (Pluggable Authentication Modules) is a system security tool that
allows system administrators to set authentication policy without
having to recompile programs that handle authentication.

---------------------------------------------------------------------
Update Information:

Updated pam packages that fix a security vulnerability are now
available.

PAM (Pluggable Authentication Modules) is a system security tool that
allows system administrators to set an authentication policy without
having to recompile programs that handle authentication.

These updates fix a potential security problem present in the pam_wheel
module. These updates correct a bug in the pam_lastlog module which
prevented it from properly manipulating the /var/log/lastlog entry for
users with very high user IDs.

The pam_wheel module is used to restrict access to a particular service
based on group membership. If the pam_wheel module was used with the
"trust" option enabled, but without the "use_uid" option, any local user
would be able to spoof the username returned by getlogin(). The user
could therefore gain access to a superuser account without supplying a
password. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2003-0388 to this issue.

When manipulating the entry in /var/log/lastlog, which corresponds to a
given user, the pam_lastlog module calculates the location of the entry
by multiplying the UID and the length of an entry in the file. On some
systems, the result of this calculation would mistakenly be truncated to
32 bits for users with sufficiently high UIDs.

All users of pam should upgrade to these updated packages, which resolve
these issues.
