The Stream Control Transmission Protocol (SCTP) is used for transporting multiple streams of data at the same time between two endpoints that are connected to the same network. We presume that with enough effort it could have been exploited to run arbitrary code,” said Mozilla describing the attack vector. “A malicious peer could have modified a COOKIE-ECHO chunk in an SCTP packet in a way that potentially resulted in a use-after-free. Meanwhile, Mozilla released a security update to address a critical-rated security loophole that is tracked as CVE-2020-16044 and affects browser versions prior to Firefox 84.0.2, Firefox for Android 84.1.3, and Firefox ESR 78.6.1.

Most of the high-severity flaws are use-after-free bugs, i.e. Twelve flaws were classified as high-risk, while one was determined to be medium in severity. 141, brings 16 security fixes and while the tech giant won’t disclose details for all of them until the majority of its userbase has received the updates, it did highlight patches for 13 vulnerabilities that were reported by external researchers. Importantly, none of the flaws has been spotted as being abused in the wild. The security fixes will be rolled out to Windows, Mac, and Linux over the next few days. Google and Mozilla are each urging users to patch serious vulnerabilities in their respective web browsers, Chrome and Firefox, that could be exploited to allow threat actors to take over users’ systems. Apple Safari is not recommended for use with Pitt’s educational technology systems.Successful exploitation of some of these flaws could allow attackers to take control of vulnerable systems Google Chrome and Microsoft Edge have not yet enabled these enhanced protection settings by default, though you are able to turn them on manually. ![]() Additionally, if you clear your browser history with “site settings” checked, you will need to add Canvas to your allow list again.
