3. Problem description:

Perl is a high-level programming language commonly used for system administration utilities and Web programming.

Kevin Finisterre discovered a flaw in sperl, the Perl setuid wrapper, which can cause debugging information to be logged to arbitrary files. By setting an environment variable, a local user could cause sperl to create, as root, files with arbitrary filenames, or append the debugging information to existing files. (CVE-2005-0155)

A fix for this issue was first included in the update RHSA-2005:103 released in February 2005. However the patch to correct this issue was dropped from the update RHSA-2005:674 made in October 2005. This regression has been assigned CVE-2006-3813.

Users of Perl are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
