{"id":"CVE-2025-30216","state":"PUBLISHED","title":"CryptoLib Has Heap Overflow in Crypto_TM_ProcessSecurity due to Unchecked Secondary Header Length","description":"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. In versions 1.3.3 and prior, a Heap Overflow vulnerability occurs in the `Crypto_TM_ProcessSecurity` function (`crypto_tm.c:1735:8`). When processing the Secondary Header Length of a TM protocol packet, if the Secondary Header Length exceeds the packet's total length, a heap overflow is triggered during the memcpy operation that copies packet data into the dynamically allocated buffer `p_new_dec_frame`. This allows an attacker to overwrite adjacent heap memory, potentially leading to arbitrary code execution or system instability. A patch is available at commit 810fd66d592c883125272fef123c3240db2f170f.","publishedAt":"2025-03-25T19:22:22.645Z","updatedAt":"2025-03-25T19:37:44.551Z","severity":{"score":9.4,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["nasa CryptoLib"],"affected":[{"vendor":"nasa","product":"CryptoLib","versions":[{"version":"<= 1.3.3","status":"affected"}]}],"references":["https://github.com/nasa/CryptoLib/security/advisories/GHSA-v3jc-5j74-hcjv","https://github.com/nasa/CryptoLib/commit/810fd66d592c883125272fef123c3240db2f170f","https://github.com/user-attachments/assets/d49cea04-ce84-4d60-bb3a-987e843f09c4"],"weaknesses":["CWE-122"],"ingestedAt":"2026-10-29T20:08:55.257Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/30xxx/CVE-2025-30216.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-30216","state":"PUBLISHED","datePublished":"2025-03-25T19:22:22.645Z","dateUpdated":"2025-03-25T19:37:44.551Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-03-18T18:15:13.850Z"},"containers":{"cna":{"title":"CryptoLib Has Heap Overflow in Crypto_TM_ProcessSecurity due to Unchecked Secondary Header Length","descriptions":[{"lang":"en","value":"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.
