Summary

Tomcat could expose sensitive files or run programs if it received

specially crafted network traffic.

Software Description:

- 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.

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.

The problem can be corrected by updating your system to the following
package versions:
