Synopsis
========

A buffer overflow has been reported in Convert-UUlib, potentially
resulting in the execution of arbitrary code.

Background
==========

Convert-UUlib provides a Perl interface to the uulib library, allowing
Perl applications to access data encoded in a variety of formats.

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

    -------------------------------------------------------------------
     Package                 /  Vulnerable  /               Unaffected
    -------------------------------------------------------------------
  1  dev-perl/Convert-UUlib       < 1.051                     >= 1.051

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

A vulnerability has been reported in Convert-UUlib where a malformed
parameter can be provided by an attacker allowing a read operation to
overflow a buffer. The vendor credits Mark Martinec and Robert Lewis
with the discovery.

Impact
======

Successful exploitation would permit an attacker to run arbitrary code
with the privileges of the user running the Perl application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Convert-UUlib users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-perl/Convert-UUlib-1.051"
