Synopsis
========

Multiple vulnerabilities have been found in the PCRE Library, the worst
of which may allow remote attackers to cause a Denial of Service
condition.

Background
==========

The PCRE Library provides functions for Perl-compatible regular
expressions.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-libs/libpcre              < 8.41                     >= 8.41 

Description
===========

Multiple vulnerabilities have been discovered in The PCRE Library.
Please review the references below for details.

Impact
======

A remote attacker could possibly cause a Denial of Service condition or
other unspecified impacts via a specially crafted file.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PCRE users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-8.41"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
