Graphite 2 library (affected versions not specified)
Firefox versions prior to 53

Description
The issue is related to an out-of-bounds write in the Graphite 2 library, which can be triggered by a maliciously crafted Graphite font. This results in a potentially exploitable crash. The vulnerability can be exploited by a remote attacker to cause a denial of service.
Recommendations
For Firefox versions prior to 53, update to version 53 or later.
