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
