Heap-based buffer overflow in the
nsCaseTransformTextRunFactory::TransformString function in Mozilla Firefox
before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows
remote attackers to cause a denial of service (boolean out-of-bounds write)
or possibly have unspecified other impact via Unicode characters that are
mishandled during text conversion.
