Arch Linux Security Advisory ASA-202107-38 ========================================== Severity: Medium Date : 2021-07-20 CVE-ID : CVE-2021-36773 Package : firefox-ublock-origin Type : denial of service Remote : Yes Link : https://security.archlinux.org/AVG-2172 Summary ======= The package firefox-ublock-origin before version 1.36.2-1 is vulnerable to denial of service. Resolution ========== Upgrade to 1.36.2-1. # pacman -Syu "firefox-ublock-origin>=1.36.2-1" The problem has been fixed upstream in version 1.36.2. Workaround ========== None. Description =========== uBlock Origin before 1.36.2 supports an arbitrary depth of parameter nesting for strict blocking, which allows crafted web sites to cause a denial of service (unbounded recursion that can trigger memory consumption and a loss of all blocking functionality). Impact ====== A crafted web site could consume a lot of memory, disabling all blocking functionality.
