RHSA-2005-805: pam |

Check for the version of the pam packages Detailed Explanation for this Vulnerability Assessment An updated pam package that fixes a security weakness is now available for Red Hat Enterprise Linux 4. This update has been rated as having low security impact by the Red Hat Security Response Team. PAM (Pluggable Authentication Modules) is a system security tool that permits system administrators to set an authentication policy without having to recompile programs that handle authentication. A bug was found in the way PAM's unix_chkpwd helper program validates user passwords when SELinux is enabled. Under normal circumstances, it is not possible for a local non-root user to verify the password of another local user with the unix_chkpwd command. A patch applied that adds SELinux functionality makes it possible for a local user to use brute force password guessing techniques against other local user accounts. The Common Vulnerabilities and Exposures project has assigned the name CVE-2005-2977 to this issue. All users of pam should upgrade to this updated package, which contains backported patches to correct these issues.
