A specially crafted truncated JSON document whose final structural token closes a nested array or object can cause json_iterator::walk_document() to access buf[len] after the input buffer has been exhausted. This results in a heap out-of-bounds read and may cause application termination, leading to denial of service.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/simdjson/simdjson/commit/20b28712ffce8320237b75a587d35a2e89140577","tags":[]},{"url":"https://github.com/simdjson/simdjson/issues/2815","tags":[]},{"url":"https://github.com/simdjson/simdjson/pull/2817","tags":[]},{"url":"https://github.com/simdjson/simdjson/issues/2815","tags":[]}],"exploitRefs":[{"url":"https://github.com/simdjson/simdjson/commit/20b28712ffce8320237b75a587d35a2e89140577","tags":[]},{"url":"https://github.com/simdjson/simdjson/issues/2815","tags":[]},{"url":"https://github.com/simdjson/simdjson/pull/2817","tags":[]},{"url":"https://github.com/simdjson/simdjson/issues/2815","tags":[]}],"hasPoc":true,"ai":null}
