Synopsis
========

Multiple vulnerabilities were found in Perl, the worst of which could
allow a local attacker to cause a Denial of Service condition.

Background
==========

Perl is Larry Wall's Practical Extraction and Report Language.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-lang/perl              < 5.12.3-r1              >= 5.12.3-r1

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

Multiple vulnerabilities have been discovered in Perl. Please review
the CVE identifiers referenced below for details.

Impact
======

A local attacker could cause a Denial of Service condition or perform
symlink attacks to overwrite arbitrary files with the privileges of the
user running the application. A context-dependent attacker could cause
a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Perl users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/perl-5.12.3-r1"
