RHSA-2003-262: pam_smb Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the pam_smb packages

Detailed Explanation for this Vulnerability Test

Updated pam_smb packages are now available which fix a security
vulnerability (buffer overflow).

The pam_smb module is a pluggable authentication module (PAM) used to
authenticate users using an external Server Message Block (SMB) server.

A buffer overflow vulnerability has been found that affects unpatched
versions of pam_smb up to and including 1.1.6.

On systems that use pam_smb and are configured to authenticate a
remotely accessible service, a possible hacker can exploit this bug and
remotely execute arbitrary code. The Common Vulnerabilities and Exposures
project ( has assigned the name CVE-2003-0686 to this issue.

Red Hat Enterprise Linux contains a version of pam_smb that is vulnerable
to this issue, however pam_smb is not enabled by default.

Users of pam_smb are advised to upgrade to these erratum packages, which
contain a patch to version 1.1.6 to correct this issue.

Red Hat would like to thank Dave Airlie of the Samba team for notifying us
of this issue.
