Synopsis
========

Multiple vulnerabilities have been found in libwww-perl, the worst of
which could allow attackers to execute arbitrary code.

Background
==========

libwww is a collection of Perl modules providing a consistent interface
to the World-Wide Web.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-perl/libwww-perl         < 6.30.0                  >= 6.30.0 

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

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

Impact
======

A remote attacker could entice a user to download a specially-crafted
file with an application linked against libwww-perl, which could result
in overwritten files or arbitrary code execution by writing to a
dotfile in the user's home directory (such as .bashrc). Additionally, a
remote attacker could perform a Man-in-the-Middle attack.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libwww-perl users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-perl/libwww-perl-6.30.0"
