Ubuntu Linux packages fixed risk of unauthorized code execution

CVE-2023-53791 · published 5 days ago
Summary

The Linux packages for Ubuntu 22.04, including the standard version and cloud‑specific versions, have been updated to close a flaw that could let an attacker run their own code on the system. If left unpatched, this could give a malicious party control over the server. Install the latest Ubuntu updates as soon as possible.
