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:

  ftp://ftp.turbolinux.com/pub/updates/6.0/security/LPRng-3.6.26-1.i386.rpm

  The source RPM can be downloaded here:

  ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/LPRng-3.6.26-1.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
