Synopsis
========

A vulnerability in XStream may allow remote attackers to execute
arbitrary code.

Background
==========

XStream is a simple library to serialize objects to XML and back again.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-java/xstream            < 1.4.8-r1               >= 1.4.8-r1

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

It was found that XStream would deserialize arbitrary user-supplied XML
content, thus representing objects of any type.

Impact
======

A remote attacker could pass a specially crafted XML document to
XStream, possibly resulting in the execution of arbitrary code with the
privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All XStream users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-java/xstream-1.4.8-r1"
