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

1. Problem Summary(From the FreeBSD, Inc. Advisory)

The LPRng port, versions prior to 3.6.26, contains a potential vulnera- bility which may allow root compromise from both local and remote systems. The vulnerability is due to incorrect usage of the syslog(3) function. Local and remote users can send string-formatting operators to the print- er daemon to corrupt the daemon's execution, potentially gaining root access.

2. Impact(From the FreeBSD, Inc. Advisory)

Local and remote users may potentially gain root privileges on systems using LPRng.

If you have not chosen to install the LPRng port/package, then your system is not vulnerable to this problem.

3. Solution

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

rpm -Uvh --nodeps --force ftp_path_to_filename

Where ftp_path_to_filename is the following:


The source RPM can be downloaded here:


**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:


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.
