 Package : ublock-origin Version : 1.62.0+dfsg-0+deb11u1 CVE ID : CVE-2025-4215 Debian Bug : 1104635

 A flaw was found in ublock-origin, a lightweight and efficient ads, malware, trackers blocker. A remote attacker could abuse an inefficient regular expression in ublock-origin's filters to cause a denial-of-service and freeze a web browser.
