Summary: USN-3991-2 caused a regression in Firefox
USN-3991-1 fixed vulnerabilities in Firefox, and USN-3991-2 fixed a
subsequent regression. The update caused an additional regression that
resulted in Firefox failing to load correctly after executing it in safe

sensitive information, conduct cross-site scripting (XSS) attacks, or
execute arbitrary code. (CVE-2019-11691, CVE-2019-11692,

Mozilla: Use-after-free of ChromeEventHandler by DocShell
A use-after-free vulnerability can occur in the chrome event handler when it is freed while still in use. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
Statement: In general, this flaw cannot be exploited through email in Thunderbird because scripting is disabled when reading mail, but it is potentially a risk in browser or browser-like contexts.
