Package        : libhtmlcleaner-java
Version        : 2.21-5+deb10u1
CVE ID         : CVE-2023-34624

A security vulnerability has been discovered in libhtmlcleaner-java, a Java
HTML parser library. An attacker was able to cause a denial of service
(StackOverflowError) if the parser runs on user supplied input with deeply
nested HTML elements. This update introduces a new nesting depth limit
which can be overridden in cleaner properties.

For Debian 10 buster, this problem has been fixed in version
2.21-5+deb10u1.

We recommend that you upgrade your libhtmlcleaner-java packages.
