Multiple integer overflows in mcrypt.c in the mcrypt extension in PHP
before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 allow remote
attackers to cause a denial of service (heap-based buffer overflow and
application crash) or possibly have unspecified other impact via a crafted
length value, related to the (1) mcrypt_generic and (2) mdecrypt_generic
functions.
