The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.

CVE-2016-4303 [CRITICAL] CVE-2016-4303 iperf3: JSON parsing vulnerability
CVE-2016-4303 iperf3: JSON parsing vulnerability
A bug exists in the way that the included version of the cjson library
handles Unicode literals in JSON string constants. A malformed
Unicode literal can cause a process parsing a block of JSON to
overwrite a pre-allocated buffer in the heap. Note that this bug has
already been fixed in recent versions of cjson.
A malicious process can connect to an iperf3 server and, by sending a
malformed message on the control channel, corrupt the server process's
heap area. This can lead to a crash (and a denial of service), or
theoretically a remote code execution as the user running the iperf3
server. A malicious iperf3 server could potentially mount a similar
attack on an iperf3 client.

## Abstract
Software vulnerabilities continue to be ubiquitous, even in the era of AI-powered code assistants, advanced static analysis tools, and the adoption of extensive testing frameworks. It has become apparent that we must not simply prevent these bugs, but also eliminate them in a quick, effi
