CVSS: 4.3EPSS: 0%CPEs: 3EXPL: 1CVE-2013-1055 – Potential DoS through abuse of rate limit in libunity-webapps for Firefox
https://notcve.org/view.php?id=CVE-2013-1055
07 Apr 2021 — The unity-firefox-extension package could be tricked into dropping a C callback which was still in use, which Firefox would then free, causing Firefox to crash. This could be achieved by adding an action to the launcher and updating it with new callbacks until the libunity-webapps rate limit was hit. Fixed in 3.0.0+14.04.20140416-0ubuntu1.14.04.1 of unity-firefox-extension and in all versions of libunity-webapps by shipping an empty unity-firefox-extension package, thus disabling the extension entirely and ... • https://launchpad.net/bugs/1175691 • CWE-404: Improper Resource Shutdown or Release •

CVSS: 7.8EPSS: 0%CPEs: 8EXPL: 0CVE-2021-3444 – Linux kernel bpf verifier incorrect mod32 truncation
https://notcve.org/view.php?id=CVE-2021-3444
23 Mar 2021 — The bpf verifier in the Linux kernel did not properly handle mod32 destination register truncation when the source register was known to be 0. A local attacker with the ability to load bpf programs could use this gain out-of-bounds reads in kernel memory leading to information disclosure (kernel memory), and possibly out-of-bounds writes that could potentially lead to code execution.
