Synopsis:          Moderate: perl security update
Advisory ID:       RHSA-2005:881-01
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2005-881.html
Issue date:        2005-12-20
Updated on:        2005-12-20
Product:           Red Hat Enterprise Linux
CVE Names:         CVE-2004-0976 CVE-2005-0448 CVE-2005-3962
- ---------------------------------------------------------------------

1. Summary:

Updated Perl packages that fix security issues and bugs are now available
for Red Hat Enterprise Linux 3.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

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

An integer overflow bug was found in Perl's format string processor.  It is
possible for an attacker to cause perl to crash or execute arbitrary code
if the attacker is able to process a malicious format string.  This issue
is only exploitable through a script wich passes arbitrary untrusted
strings to the format string processor.  The Common Vulnerabilities and
Exposures project assigned the name CVE-2005-3962 to this issue.

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.  (CVE-2005-0448)

Solar Designer discovered several temporary file bugs in various Perl
modules.  A local attacker could overwrite or create files as the user
running a Perl script that uses a vulnerable module.  (CVE-2004-0976)

Users of Perl are advised to upgrade to these updated packages, which
contain backported patches to correct these issues as well as fixes for
several bugs.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
