Ubuntu has issued two security updates: USN-7713-1 addressing vulnerabilities in OpenLDAP and USN-7710-2 resolving a vulnerability in Python 2.7. The OpenLDAP update affects Ubuntu 14.04 LTS, while the Python update affects Ubuntu versions 16.04 LTS, 18.04 LTS, 20.04 LTS, and 22.04 LTS. The resolved issues encompass the incorrect parsing of X.509 DNs by OpenLDAP, which had the potential to lead to a denial of service (CVE-2020-36229, CVE-2020-36230), as well as the inefficient parsing of maliciously crafted HTML input and Tar archives by Python (CVE-2025-6069, CVE-2025-8194).
