"The plain text serializer used a fixed-size array for the number of ol
elements it could process; however it was possible to overflow the
static-sized array leading to memory corruption and a potentially
exploitable crash. This vulnerability affects Thunderbird < 68.3,
Firefox ESR < 68.3, and Firefox < 71. (CVE-2019-17005)

Under certain conditions, when checking the Resist Fingerprinting
preference during device orientation checks, a race condition could
have caused a use-after-free and a potentially exploitable crash. This
vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and
Firefox < 71. (CVE-2019-17010)

When using nested workers, a use-after-free could occur during worker
destruction. This resulted in a potentially exploitable crash. This
vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and
Firefox < 71. (CVE-2019-17008)

Mozilla developers reported memory safety bugs present in Firefox 70
and Firefox ESR 68.2. 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. This vulnerability affects
Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
(CVE-2019-17012)

Under certain conditions, when retrieving a document from a DocShell
in the antitracking code, a race condition could cause a
use-after-free condition and a potentially exploitable crash. This
vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and
Firefox < 71. (CVE-2019-17011)");
