CVE-2022-34169

Name of the Vulnerable Software and Affected Versions Apache Xalan Java XSLT library versions prior to 2.7.3

Description The Apache Xalan Java XSLT library is vulnerable to an integer truncation issue when processing malicious XSLT stylesheets. This can be used to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode. Note that Java runtimes, such as OpenJDK, include repackaged copies of Xalan.

Recommendations To resolve the issue, update to version 2.7.3 or later. As a temporary workaround, consider restricting the processing of malicious XSLT stylesheets until a patch is available.
