Details

USN-8369-1 fixed a vulnerability in mod_jk. It was discovered that for Ubuntu 18.04 LTS, during the update preparation phase, a previous fix for CVE-2023-41081 was incorrectly dropped. This update reintroduces the fix for CVE-2023-41081.

We apologize for the inconvenience.

Original advisory details:

It was discovered that Apache Tomcat Connectors used incorrect default permissions for shared memory on Unix-like systems. A local attacker could possibly use this issue to view or modify mod_jk configuration data in shared memory, resulting in sensitive information exposure or a denial of service.
