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.
