Apache Santuario, XML Security for Java, is vulnerable to an issue where the secureValidation property is not passed correctly when creating a KeyInfo from a KeyInfoReference element. This allows an attacker to abuse an XPath Transform to extract any local .xml files in a RetrievalMethod element.

For Debian 9 stretch, this problem has been fixed in version 1.5.8-2+deb9u1.

We recommend that you upgrade your libxml-security-java packages.
