Synopsis
========
Insufficient constraints in Apache's Xalan-Java might allow remote
attackers to execute arbitrary code and load arbitrary classes.
Background
==========
Xalan-Java is an XSLT processor for transforming XML documents into
HTML, text, or other XML document types.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-java/xalan < 2.7.2 >= 2.7.2
Description
===========
The TransformerFactory in Apache Xalan-Java does not properly restrict
access to certain properties when FEATURE_SECURE_PROCESSING is enabled.
This can also be exploited via a Java property that is bound to the
XSLT 1.0 system-property function.
Impact
======
A remote attacker could inject specially crafted XSLT properties
resulting in the execution of arbitrary code with the privileges of the
process.
Workaround
==========
There is no known work around at this time.
Resolution
==========
All Xalan-Java users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/xalan-2.7.2"
References
