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. 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: ftp://ftp.turbolinux.com/pub/updates/4.0/security/perl-5.00503-7.i386.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/security/perl-5.005_02-8TL.i386.rpm The source RPM can be downloaded here: ftp://ftp.turbolinux.com/pub/updates/4.0/SRPMS/perl-5.005_02-8TL.src.rpm ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/perl-5.00503-7.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.
