_______________
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
Update the packages from our ftp server by running the following
command:
rpm -Uvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/cvsweb-1.93-1.noarch.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/cvsweb-1.93-1.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 checksums of the updates before you install:
MD5 sum Package Name
