Denial-of-Service Memory Exhaustion

Overview

Versions prior to 1.0 of qs are affected by a denial of service condition. This condition is triggered by parsing a crafted string that deserializes into very large sparse arrays, resulting in the process running out of memory and eventually crashing.

Recommendation

Update to version 1.0.0 or later.
