Synopsis
========
Multiple vulnerabilities have been found in Expat, the worst of which
may allow execution of arbitrary code.

Background
==========
Expat is a set of XML parsing libraries.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-libs/expat < 2.2.0-r1 >= 2.2.0-r1

Description
===========
Multiple vulnerabilities have been discovered in Expat. Please review
the CVE identifiers referenced below for details.

Impact
======
A remote attacker, by enticing a user to process a specially crafted
XML file, could execute arbitrary code with the privileges of the
process or cause a Denial of Service condition. This attack could also
be used against automated systems that arbitrarily process XML files.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Expat users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/expat-2.2.0-r1"
