Synopsis
========

An integer overflow in LZO might allow remote attackers to execute
arbitrary code or cause a Denial of Service condition.

Background
==========

LZO is an extremely fast compression and decompression library

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-libs/lzo                  < 2.08                     >= 2.08

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

LZO is vulnerable to an integer overflow condition in the
"lzo1x_decompress_safe" function which could result in a possible
buffer overrun when processing maliciously crafted compressed input
data.

Impact
======

A remote attacker could send specially crafted compressed input data
possibly resulting in a Denial of Service condition or arbitrary code
execution.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All LZO users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-libs/lzo-2.08"
