Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

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.
