_____________________________________________________________________________________________
A security hole has been discovered in the xntp3 packages. Please
update the packages in your installation as soon as possible.
_____________________________________________________________________________________________
1. Problem Summary
A remote buffer overflow vulnerability exists in the network time
protocol daemon. It is remotely exploitable and a user with
malicious intent can crash the daemon or execute arbitrary code on
the affected host.
2. Impact
Remote exploitation can result in an attacker gaining remote root
access or a denial of ntp service on the affected system.
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/xntp3-5.93-10.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/xntp3-server-5.93-10.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/xntp3-5.93-10.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

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.
