1. Topic:
Under some network configurations PAM (Pluggable Authentication Modules) will fail to lock access to disabled NIS accounts.

2. Problem description:
The PAM packages shipped with Red Hat Linux 6.1/Intel may allow access to locked NIS accounts on certain network configurations. If you have a Red Hat Linux 6.1 workstation performing authentication against a NIS server then you are at risk. Red Hat recommends that you upgrade the PAM packages on all Red Hat Linux 6.1 workstations to the versions announced in this advisory.

Previous versions of Red Hat Linux are not affected by this problem.

7. RPMs required:

Intel:

pam-0.68- 8.i386.rpm

Source:

pam-0.68- 8.src.rpm

Architecture neutral:

8. Solution:
For each RPM for your particular architecture, run:

e8d5b9edf5dc9998ee19d91b7620f2ad  i386/pam-0.68-8.i386.rpm
 

You can verify each package with the following command:

rpm --checksig filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command:

rpm --checksig --nogpg filename
