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 Credits: Michal Zalewski, Simon Cozens
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
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.
The latest versions of perl as well as past shipping versions of perl in TurboLinux distributions are susceptible to a local root exploit.
Please upgrade your packages to match the new revision
