1.148. pam

Updated pam packages that fix a bug in the pam_time and pam_group modules are now available.

Pluggable Authentication Modules (PAM) provide a system whereby administrators can set up authentication policies, without having to recompile programs to handle authentication.

These updated packages fix the following bug:

* the pam_time and pam_group modules, which support allowing or rejecting authentication based on time and assigning group names respectively, incorrectly matched user, service, or terminal name substrings even if no wildcard was specified in the configuration. For example, "user" and "user1" were incorrectly equated, causing policies to apply to both usernames even when "user" was the only username subject to said policies. This update improves the string matching in the pam_time and pam_group modules ensuring such mis-matches (and consequent policy mis-applications) no longer occur. (BZ#571341)

All pam users are advised to upgrade to these updated packages, which resolve this issue.
