Red Hat Security Advisory

Synopsis: Low: perl security update
Advisory ID: RHSA-2005:674-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-674.html
Issue date: 2005-10-05
Updated on: 2005-10-05
Product: Red Hat Enterprise Linux
CVE Names: CAN-2005-0448
- ---------------------------------------------------------------------

1. Summary:

Updated Perl packages that fix security issues and contain several bug
fixes are now available for Red Hat Enterprise Linux 4.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied. Use Red Hat
Network to download and update your packages. To launch the Red Hat
