Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

mongodb developers report :

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.
