An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-29913 exists.\n\nAffected product: nasa CryptoLib. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-29913/ (Markdown: https://insights.sbomify.com/CVE-2025-29913/index.md)","id":"CVE-2025-29913","markdown":"https://insights.sbomify.com/CVE-2025-29913/index.md","name":"CVE-2025-29913","record":{"aliases":["GHSA-q4v2-fvrv-qrf6"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"NASA CryptoLib","requires_auth":"none","summary":"An attacker can cause a heap buffer overflow and potential code execution in NASA CryptoLib by sending a malicious telecommand frame that triggers an integer underflow.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"cryptolib","vendor":"nasa"}],"cvss":{"score":8.9,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-191","name":"Integer Underflow (Wrap or Wraparound)"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"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. A critical heap buffer overflow vulnerability was identified in the `Crypto_TC_Prep_AAD` function of CryptoLib versions 1.3.3 and prior. This vulnerability allows an attacker to trigger a Denial of Service (DoS) or potentially execute arbitrary code (RCE) by providing a maliciously crafted telecommand (TC) frame that causes an unsigned integer underflow. The vulnerability lies in the function `Crypto_TC_Prep_AAD`, specifically during the computation of `tc_mac_start_index`. The affected code incorrectly calculates the MAC start index without ensuring it remains within the bounds of the `ingest` buffer. When `tc_mac_start_index` underflows due to an incorrect length calculation, the function attempts to access an out-of-bounds memory location, leading to a segmentation fault. The vulnerability is still present in the repository as of commit `d3cc420ace96d02a5b7e83d88cbd2e48010d5723`.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"CryptoLib's Crypto_TC_Prep_AAD Has Buffer Overflow Due to Integer Underflow","id":"CVE-2025-29913","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"OWASP Coraza WAF has parser confusion which leads to wrong URI in `REQUEST_FILENAME`","id":"CVE-2025-29914"},"packages":[],"prev":{"headline":"CryptoLib Has Heap Buffer Overflow Due to Unsigned Integer Underflow in Crypto_TC_ProcessSecurity","id":"CVE-2025-29912"},"products":["CryptoLib"],"published":"2025-03-17","related":[{"cvss_score":9.4,"headline":"CryptoLib Has Heap Overflow in Crypto_TM_ProcessSecurity due to Unchecked Secondary Header Length","id":"CVE-2025-30216","kev_date_added":null,"published":"2025-03-25"},{"cvss_score":9.3,"headline":"Heap Buffer Overflow via Incomplete Length Check in `Crypto_TC_ApplySecurity`","id":"CVE-2025-30356","kev_date_added":null,"published":"2025-04-01"},{"cvss_score":8.9,"headline":"CryptoLib's Crypto_TC_ApplySecurity() Has a Heap Buffer Overflow Vulnerability","id":"CVE-2025-29909","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.9,"headline":"CryptoLib Has Heap Buffer Overflow in Crypto_AOS_ProcessSecurity Function","id":"CVE-2025-29911","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.9,"headline":"CryptoLib Has Heap Buffer Overflow Due to Unsigned Integer Underflow in Crypto_TC_ProcessSecurity","id":"CVE-2025-29912","kev_date_added":null,"published":"2025-03-17"},{"cvss_score":8.8,"headline":"CryptoLib vulnerable to Stack Buffer Overflow in Crypto_Key_Update due to missing TLV length check","id":"CVE-2025-64096","kev_date_added":null,"published":"2025-10-30"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-03-18","vendors":["nasa"]},"summary":"An attacker can cause a heap buffer overflow and potential code execution in NASA CryptoLib by sending a malicious telecommand frame that triggers an integer underflow.","url":"https://insights.sbomify.com/CVE-2025-29913/"}
