Severity: Normal
Title: Xalan-Java: Arbitrary code execution
Date: April 02, 2016
Bugs: #505602
ID: 201604-02

– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –

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
