Package        : libhtmlcleaner-java
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 the oldstable distribution (bullseye), this problem has been fixed
in version 2.24-1+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in
version 2.26-1+deb12u1.

We recommend that you upgrade your libhtmlcleaner-java packages.
