There is no check on the size given to malloc, e.g., -1 is accepted. This allocates a chunk of size zero, which will give a heap pointer. However, one can send 0xffffffff bytes of data, which can have a DoS impact or lead to remote code execution.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2022-01-27T00:19:56.000000Z"}, {"uuid": "2529a089-ee43-4c3f-8bc2-7215a14fc81d", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2022-23967", "type": "published-proof-of-concept", "source": "https://t.me/BlueRedTeam/1668", "content": "#exploit\n1.
