Ubuntu 20.04 LTS, and Ubuntu 18.04 LTS. This update fixes it for
tomcat9 in Ubuntu 24.04 LTS, Ubuntu 24.10, and Ubuntu 25.10.
These versions include only the tomcat library (libtomcat9-java)
and not the full tomcat server stack.

Original advisory details:

It was discovered that Apache Tomcat incorrectly implemented partial
PUT functionality by replacing path separators with dots in temporary
files. A remote attacker could possibly use this issue to access
sensitive files, inject malicious content, or execute remote code.");
