The bcpowmod function in ext/bcmath/bcmath.c in PHP before 5.5.35, 5.6.x
before 5.6.21, and 7.x before 7.0.6 modifies certain data structures
without considering whether they are copies of the zero, one, or two
global variable, which allows remote attackers to cause a denial of service
or possibly have unspecified other impact via a crafted call.
