Updated thunderbird packages fix security vulnerabilities: A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash (CVE-2020-6831). A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This resulted in a potentially exploitable crash (CVE-2020-12387). The βCopy as cURLβ feature of Devtoolsβ network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the βCopy as cURLβ feature and pasted the command into a terminal, it could have resulted in the disclosure of local files (CVE-2020-12392). Mozilla developers and community members Alexandru Michis, Jason Kratzer, philipp, Ted Campbell, Bas Schouten, AndrΓ© Bargull, and Karl Tomlinson reported memory safety bugs present in Thunderbird ESR 68.7. 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 (CVE-2020-12395). By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays (CVE-2020-12397).
