Package        : libxml-security-java
Version        : 1.5.8-2+deb9u1
CVE ID         : CVE-2021-40690
Debian Bug     : 994569

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.

For the detailed security status of libxml-security-java please refer to
