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-2026-34180 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-2026-34180/ (Markdown: https://insights.sbomify.com/CVE-2026-34180/index.md)","id":"CVE-2026-34180","markdown":"https://insights.sbomify.com/CVE-2026-34180/index.md","name":"CVE-2026-34180","record":{"aliases":["ALPINE-CVE-2026-34180","AZL-89796","AZL-89855","AZL-89940","BELL-CVE-2026-34180","CLEANSTART-2026-LF37646","DEBIAN-CVE-2026-34180","GHSA-3c8f-qq7h-7qv6","JLSEC-2026-1133","MINI-6qxv-32hh-x395","MINI-8mv2-hvr9-qw76","ROOT-OS-ALPINE-315-CVE-2026-34180","ROOT-OS-ALPINE-317-CVE-2026-34180","UBUNTU-CVE-2026-34180"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL library","requires_auth":"none","summary":"Attackers can cause denial of service or information disclosure via heap buffer over-read in OpenSSL's ASN.1 parser when processing crafted DER data.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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-125","name":"Out-of-bounds Read"}],"description":"Issue summary: Parsing a crafted DER-encoded ASN.1 structure with a primitive\nelement whose content exceeds 2 gigabytes in length may cause a heap buffer\nover-read on 64-bit Unix and Unix-like platforms.\n\nImpact summary: The heap buffer over-read may crash the application (Denial of\nService) or to load into the decoded ASN.1 object contents of memory beyond the\nend of the input buffer.
