                        TurboLinux Security Announcement

Package: pam-0.70-2 and earlier (UPDATED -- includes 0.72-4) Date: Fri Aug 10 15:00 PDT 2000
Affected TurboLinux versions: 6.0.5 and earlier Vulnerability Type: Denial of Service possible (updated) TurboLinux Advisory ID#: TLSA2000009-2 BugTraq ID#: 913 Credits: This vulnerability was posted to Bugtraq in a L0pht security advisory written by Dildog on January 4, 2000.

A security hole was discovered in the packages mentioned above. Please update the packages in your installation as soon as possible or disable the service.


1. Problem Summary

This is an update to TurboLinux Security Advisory TLSA2000009-1. Our pam package (0.70 up to and including 0.72-4) incorrectly lacked one configuration file (/etc/pam.d/other).

2. Impact

A denial of service attack can be made against the PAM auth system.

3. Solution

Update the packages from our ftp server by running the following command:

rpm -Fvh ftp_path_to_filename

Where ftp_path_to_filename is the following:

ftp://ftp.turbolinux.com/pub/updates/6.0/security/pam-0.72-5.i386.rpm

The source rpm can be downloaded here:

ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/pam-0.72-5.src.rpm

**Note: You must rebuild and install the rpm if you choose to download and install the srpm. Simply installing the srpm alone WILL NOT CLOSE THE SECURITY HOLE.

Please verify the md5 checksum of the update before you install:

  MD5 sum                               Package Name

71372020a4dadeed1ad28d9b46df35da pam-0.72-5.i386.rpm
dd700e6dff00ca5861b01758838166a8 pam-0.72-5.src.rpm

These packages are GPG signed by Turbolinux for security. Our key is available here:

http://www.turbolinux.com/security/tlgpgkey.asc

To verify a package, use the following command:

rpm --checksig name_of_rpm

To examine only the md5sum, use the following command:

rpm --checksig --nogpg name_of_rpm

**Note: Checking GPG keys requires RPM 3.0 or higher.
