Descriptions

[Json-smart](https://netplex.github.io/json-smart/) is a performance focused, JSON processor lib.

When reaching a ‘[‘ or ‘{‘ character in the JSON input, the code parses an array or an object respectively.

It was discovered that the code does not have any limit to the nesting of such arrays or objects. Since the parsing of nested arrays and objects is done recursively, nesting too many of them can cause a stack exhaustion (stack overflow) and crash the software.

A flaw was found in the json-smart package. This security flaw occurs when reaching a ‘[‘ or ‘{‘ character in the JSON input, and the code parses an array or an object, respectively. The 3PP does not have any limit to the nesting of such arrays or objects. Since nested arrays and objects are parsed recursively, nesting too many of them can cause stack exhaustion (stack overflow) and crash the software.
