AI-suggested

Apply the official patches provided by Ubuntu as detailed in security notice USN-7786-1. Updating to the fixed package versions listed in the advisory will remediate the vulnerability. No additional mitigation is required beyond applying these updates.

Description

A vulnerability in OpenSSL's handling of CMS messages encrypted with password-based encryption can cause out-of-bounds read and write errors. This may lead to application crashes (Denial of Service) or memory corruption, potentially allowing execution of attacker-supplied code. The vulnerability is considered critical with a CVSS score of 9.8. The issue affects multiple Ubuntu package versions of OpenSSL but does not impact the FIPS modules. Patches are available and should be applied to mitigate the risk.
