An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-15467 exists.\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-2025-15467/ (Markdown: https://insights.sbomify.com/CVE-2025-15467/index.md)","id":"CVE-2025-15467","markdown":"https://insights.sbomify.com/CVE-2025-15467/index.md","name":"CVE-2025-15467","record":{"aliases":["ALPINE-CVE-2025-15467","AZL-75791","AZL-75908","BELL-CVE-2025-15467","CLEANSTART-2026-VU59374","DEBIAN-CVE-2025-15467","ECHO-decb-8594-a95c","GHSA-wvhq-3h88-rf6g","JLSEC-2026-256","MINI-3f28-p62q-7h2x","MINI-mp9j-f499-pfq3","MINI-mxh7-mw93-fg88","OESA-2026-1310","OESA-2026-1311","OESA-2026-1312","OESA-2026-1391","OESA-2026-1392","OESA-2026-1393","OESA-2026-1394","UBUNTU-CVE-2025-15467"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"Attackers can trigger a stack buffer overflow in OpenSSL by sending crafted CMS messages with oversized IVs, potentially causing crashes or remote code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"},{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Issue summary: Parsing CMS AuthEnvelopedData or EnvelopedData message with\nmaliciously crafted AEAD parameters can trigger a stack buffer overflow.\n\nImpact summary: A stack buffer overflow may lead to a crash, causing Denial\nof Service, or potentially remote code execution.\n\nWhen parsing CMS (Auth)EnvelopedData structures that use AEAD ciphers such as\nAES-GCM, the IV (Initialization Vector) encoded in the ASN.1 parameters is\ncopied into a fixed-size stack buffer without verifying that its length fits\nthe destination.
