                        TurboLinux Security Announcement

        Package: perl-5.00503 and earlier
        Date: Wednesday August 9 17:00 PDT 2000

        Affected TurboLinux versions: 6.0.5 and earlier (including 4.x)
        Vulnerability Type: Local root exploit
        TurboLinux Advisory ID#:  TLSA2000018-1

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

1. Problem Summary

A component of perl, sperl, runs suid root to enable execution of perl code
by a file's owner. When sperl is used in an improper manner, it will alert
the root user via /bin/mail that illegal use of sperl has been attempted. A
widely available exploit utilizes this behavior to gain privileged access.

2. Impact

The latest versions of perl as well as past shipping versions of perl in
TurboLinux distributions are susceptible to a local root exploit.

3. Solution

Please upgrade your packages 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 for 4.x or 6.x versions:


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

Please verify the MD5 checksum of the update before you install:
