perl security update

CentOS Errata and Security Advisory CESA-2005:674

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

Paul Szabo discovered a bug in the way Perl’s File::Path::rmtree module
removed directory trees. If a local user has write permissions to a
subdirectory within the tree being removed by File::Path::rmtree, it is
possible for them to create setuid binary files. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0448
to this issue.

This update also addresses the following issues:

– Perl interpreter caused a segmentation fault when environment
changes occurred during runtime.

– Code in lib/FindBin contained a regression that caused problems with
MRTG software package.

– Perl incorrectly declared it provides an FCGI interface where it in fact
did not.

Users of Perl are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
