CVE-2020-6800 Information

Description

Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. In general these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird 68.5 Firefox 73 and Firefox ESR68.5.
