CVE-2017-7845
A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics library, used for WebGL content.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.17%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics library, used for WebGL content. This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Thunderbird < 52.5.2, Firefox ESR < 52.5.2, and Firefox < 57.0.2.
