Gentoo: 201604-02 Normal: Xalan-Java Arbitrary Code Execution
gentoo
April 2, 2016
Insufficient constraints in Apache's Xalan-Java might allow remote attackers to execute arbitrary code and load arbitrary classes.
Summary
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.
Resolution
All Xalan-Java users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-java/xalan-2.7.2"
