Fedora Legacy Update Advisory

Synopsis: Updated pcre packages fix a security issue
Advisory ID: FLSA:168516
Issue date: 2006-03-07
Product: Red Hat Linux, Fedora Core
Keywords: Bugfix
CVE Names: CVE-2005-2491
---------------------------------------------------------------------

---------------------------------------------------------------------
1. Topic:

Updated pcre packages are now available to correct a security issue.

PCRE is a Perl-compatible regular expression library.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386
Fedora Core 2 - i386

3. Problem description:

An integer overflow flaw was found in PCRE, triggered by a maliciously
crafted regular expression. On systems that accept arbitrary regular
expressions from untrusted users, this could be exploited to execute
arbitrary code with the privileges of the application using the library.
The Common Vulnerabilities and Exposures project assigned the name
CVE-2005-2491 to this issue.

Users should update to these erratum packages that contain a backported
patch to correct this issue.

4. Solution:

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which
are not installed but included in the list will not be updated. Note
that you can also use wildcards (*.rpm) if your current directory *only*
contains the desired RPMs.

Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.

These packages are GPG signed by Fedora Legacy for security. Our key is
available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v lt;filenamegt;

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the sha1sum with the following command:

sha1sum lt;filenamegt;
