NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by RHEL.
See How to fix? for RHEL:6 relevant fixed versions and status.
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
