 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
=========
