Test ID:1.3.6.1.4.1.25623.1.0.55253
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2005:761
Summary:NOSUMMARY
Description:Description:

The remote host is missing updates announced in
advisory RHSA-2005:761.

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 privileges 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 allow a user who already has the ability to write .htaccess
files to gain 'apache' privileges. 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.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
