CVE-2019-9796

Priority
Description
A use-after-free vulnerability can occur when the SMIL animation controller
incorrectly registers with the refresh driver twice when only a single
registration is expected. When a registration is later freed with the
removal of the animation controller element, the refresh driver incorrectly
leaves a dangling pointer to the driver's observer array. This
vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <
66.
