A use-after-free vulnerability can occur when flushing and resizing layout
because the “PressShell” object has been freed while still in use. This
results in a potentially exploitable crash during these operations. This
vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird <
52.5.
