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"
