## Description

The AnimationThread function in Mozilla Firefox before 41.0 and Firefox ESR
38.x before 38.3 uses an incorrect argument to the sscanf function, which
might allow remote attackers to cause a denial of service (stack-based
buffer overflow and application crash) or possibly have unspecified other
impact via unknown vectors.
