In 1.3.3 and earlier, a heap buffer overflow vulnerability persists in the Crypto_TC_ApplySecurity function due to an incomplete validation check on the fl (frame length) field. Although CVE-2025-29912 addressed an underflow issue involving fl, the patch fails to fully prevent unsafe calculations. As a result, an attacker can still craft malicious frames that cause a negative tf_payload_len, which is then interpreted as a large unsigned value, leading to a heap buffer overflow in a memcpy call.\n\ud83d\udccf Published: 2025-04-01T22:06:22.576Z\n\ud83d\udccf Modified: 2025-04-01T22:06:22.576Z\n\ud83d\udd17 References:\n1. https://github.com/nasa/CryptoLib/security/advisories/GHSA-6w2x-w7w3-85w2\n2. https://github.com/nasa/CryptoLib/commit/59d1bce7608c94c6131ef4877535075b0649799c", "creation_timestamp": "2025-04-01T22:32:41.000000Z"}
