Description
===========

- CVE-2018-12389 (arbitrary code execution)

Several memory safety bugs have been found in Thunderbird versions
prior to 63.0. Some of these bugs showed evidence of memory corruption
and Mozilla engineers presume that with enough effort some of these
could be exploited to run arbitrary code.

- CVE-2018-12390 (arbitrary code execution)

Several memory safety bugs have been found in Firefox and Thunderbird
versions prior to 63.0. Some of these bugs showed evidence of memory
corruption and Mozilla engineers presume that with enough effort some
of these could be exploited to run arbitrary code.

- CVE-2018-12392 (arbitrary code execution)

A security issue has been found in Firefox and Thunderbird versions
prior to 63.0. When manipulating user events in nested loops while
opening a document through script, it is possible to trigger a
potentially exploitable crash due to poor event handling.

Impact
======

A remote attacker is able to execute arbitrary code via a specially
crafted HTML document.
