AI-suggested

A patch is available and users should update OpenSSL to the fixed package versions: 1.1.1f-1ubuntu2.24 for Ubuntu 20.04 LTS, 3.0.2-0ubuntu1.19 for Ubuntu 22.04 LTS, and 3.0.13-0ubuntu3.5 for Ubuntu 24.04 LTS. After updating, a system reboot is required to apply all changes. Refer to the Ubuntu security notice USN-7278-1 for detailed update instructions.

Description

OpenSSL contains a vulnerability (CVE-2024-9143) related to improper handling of memory operations when using low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial. This uncommon usage can allow a remote attacker to cause a crash (denial of service) or potentially execute arbitrary code. The issue is fixed in updated OpenSSL packages for Ubuntu 20.04 LTS, 22.04 LTS, and 24.04 LTS. Users should update and reboot to apply the fix.
