## Description

In MongoDB libbson 1.7.0, the bson\_iter\_codewscope function in bson-iter.c
miscalculates a bson\_utf8\_validate length argument, which allows remote
attackers to cause a denial of service (heap-based buffer over-read in the
bson\_utf8\_validate function in bson-utf8.c), as demonstrated by
bson-to-json.c.
