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"}, {"uuid": "19b9c54b-9726-4fe9-8d2c-a07044e697fb", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2025-30356", "type": "seen", "source": "https://bsky.app/profile/cyberalerts.bsky.social/post/3lls2brmaqb2p", "content": "", "creation_timestamp": "2025-04-01T23:40:24.047444Z"}, {"uuid": "99041e20-873e-44f2-8022-f9c8af6e345f", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "2a075640-a300-48a4-bb44-bc6130783b9b", "vulnerability": "CVE-2025-30356", "type": "seen", "source": "https://t.me/cvedetector/21825", "content": "{\n  \"Source\": \"CVE FEED\",\n  \"Title\": \"CVE-2025-30356 - \"CryptoLib Heap Buffer Overflow Vulnerability\"\", \n  \"Content\": \"CVE ID : CVE-2025-30356 \nPublished : April 1, 2025, 10:15 p.m. | 1\u00a0hour, 30\u00a0minutes ago \nDescription : CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station.
