Publication date: 26 May 2025
Overview: Tomcat could expose sensitive files or run programs if it received specially crafted network traffic.
Releases: 24.04 LTS

Packages
tomcat9 - Apache Tomcat 9 - Servlet and JSP engine

Details
USN-7525-1 fixed CVE-2025-24813 for tomcat9 in Ubuntu 22.04 LTS,
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.
