UBUNTU-CVE-2026-77387

geopy is a geocoding library for Python. Prior to 2.5.0, geopy.Point and Point.fromstring can spend excessive CPU time due to inefficient regular-expression behavior when an application passes a long malformed coordinate string without the 256-character input limit used by the fix. Geocoder rever...
