Synopsis
========
Multiple vulnerabilities have been found in Expat, possibly resulting
in Denial of Service.

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

Affected packages

1 dev-libs/expat < 2.1.0_beta3 >= 2.1.0_beta3

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

Impact
======
A remote attacker could entice a user to open a specially crafted XML
file in an application linked against Expat, possibly resulting in a
Denial of Service condition.

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-2.1.0_beta3"

such as revdep-rebuild may assist in identifying some of these
packages.
