RHSA-2005-761: pcre

Vulnerability Assessment Summary
Check for the version of the pcre packages

Detailed Explanation for this Vulnerability Assessment

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

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

PCRE is a Perl-compatible regular expression library.

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 rights of the application using the library.
The Common Vulnerabilities and Exposures project assigned the name
CVE-2005-2491 to this issue.

The security impact of this issue varies depending on the way that
applications make use of PCRE. For example, the Apache web server uses the
system PCRE library in order to parse regular expressions, but this flaw
would only permit a user who already has the ability to write .htaccess
files to gain 'apache' rights. For applications supplied with Red Hat
Enterprise Linux, a maximum security impact of moderate has been assigned.

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