## Description

A use-after-free can occur during buffer storage operations within the
ANGLE graphics library, used for WebGL content. The buffer storage can be
freed while still in use in some circumstances, leading to a potentially
exploitable crash. Note: This issue is in "libGLES", which is only in use
on Windows. Other operating systems are not affected. This vulnerability
affects Firefox < 52 and Thunderbird < 52.
