<= 2.13.17.5 HIGH5 MEDIUM

An issue was discovered in Jansson through 2.13.1. Due to a parsing error in json_loads, there's an out-of-bounds read-access bug. NOTE: the vendor reports that this only occurs when a programmer fails to follow the API specification

<= 2.76.5 MEDIUM5 MEDIUM

Jansson 2.7 and earlier allows context-dependent attackers to cause a denial of service (deep recursion, stack consumption, and crash) via crafted JSON data.

= 2.0, = 2.2.1, = 2.3.1, = 2.3, = 2.2, = 2.1, <= 2.4, = 2.0.15 MEDIUM

Jansson, possibly 2.4 and earlier, does not restrict the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted JSON document.
