An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-69420 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. 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-2025-69420/ (Markdown: https://insights.sbomify.com/CVE-2025-69420/index.md)","id":"CVE-2025-69420","markdown":"https://insights.sbomify.com/CVE-2025-69420/index.md","name":"CVE-2025-69420","record":{"aliases":["ALPINE-CVE-2025-69420","AZL-75269","AZL-75585","AZL-75896","AZL-76122","AZL-76167","BELL-CVE-2025-69420","CLEANSTART-2026-KG09210","DEBIAN-CVE-2025-69420","ECHO-29d0-be66-1d36","GHSA-w42r-ph9f-9x66","JLSEC-2026-264","MINI-65xw-w3w7-rq9j","MINI-7x9c-wp6r-65g2","MINI-x4mf-8hgh-9v8x","ROOT-OS-ALPINE-315-CVE-2025-69420","UBUNTU-CVE-2025-69420"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"An attacker can cause a denial of service by providing a malformed TimeStamp Response to applications using OpenSSL's verification function.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"Issue summary: A type confusion vulnerability exists in the TimeStamp Response\nverification code where an ASN1_TYPE union member is accessed without first\nvalidating the type, causing an invalid or NULL pointer dereference when\nprocessing a malformed TimeStamp Response file.\n\nImpact summary: An application calling TS_RESP_verify_response() with a\nmalformed TimeStamp Response can be caused to dereference an invalid or\nNULL pointer when reading, resulting in a Denial of Service.\n\nThe functions ossl_ess_get_signing_cert() and ossl_ess_get_signing_cert_v2()\naccess the signing cert attribute value without validating its type.\nWhen the type is not V_ASN1_SEQUENCE, this results in accessing invalid memory\nthrough the ASN1_TYPE union, causing a crash.\n\nExploiting this vulnerability requires an attacker to provide a malformed\nTimeStamp Response to an application that verifies timestamp responses.
