        Vulnerability Type: remote shell exploit
        TurboLinux Advisory ID#:  TLSA2000016-1
        Credits:

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


1. Problem Summary

Current and previous version of cvsweb allow remote users to access/write files as the default web user via the cvsweb.cgi script.

2. Impact

remote read/write access to arbitrary files owned by the default web user is possible via this exploit.

3. Solution

Please upgrade both the cvsweb package to match the new revision

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

rpm -Fv ftp_path_to_filename

Where ftp_path_to_filename is the following:

ftp://ftp.turbolinux.com/pub/updates/6.0/security/cvsweb-1.91-3.noarch.rpm

The source RPM can be downloaded here:

ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/cvsweb-1.91-3.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
