It can only be exploited from the same machine or local network, 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-2025-11187 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-2025-11187/ (Markdown: https://insights.sbomify.com/CVE-2025-11187/index.md)","id":"CVE-2025-11187","markdown":"https://insights.sbomify.com/CVE-2025-11187/index.md","name":"CVE-2025-11187","record":{"aliases":["ALPINE-CVE-2025-11187","BELL-CVE-2025-11187","CLEANSTART-2026-PD89526","CLEANSTART-2026-VP72640","DEBIAN-CVE-2025-11187","GHSA-hpc7-gcqm-58fv","JLSEC-2026-255","MINI-h554-5xj6-wrxh","MINI-rxwr-777q-phg7","UBUNTU-CVE-2025-11187"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSSL library","requires_auth":"low_privilege","summary":"Attacker can cause denial of service or potential code execution by crafting a malicious PKCS#12 file with invalid PBMAC1 parameters.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Issue summary: PBMAC1 parameters in PKCS#12 files are missing validation\nwhich can trigger a stack-based buffer overflow, invalid pointer or NULL\npointer dereference during MAC verification.\n\nImpact summary: The stack buffer overflow or NULL pointer dereference may\ncause a crash leading to Denial of Service for an application that parses\nuntrusted PKCS#12 files. The buffer overflow may also potentially enable\ncode execution depending on platform mitigations.\n\nWhen verifying a PKCS#12 file that uses PBMAC1 for the MAC, the PBKDF2\nsalt and keylength parameters from the file are used without validation.\nIf the value of keylength exceeds the size of the fixed stack buffer used\nfor the derived key (64 bytes), the key derivation will overflow the buffer.\nThe overflow length is attacker-controlled. Also, if the salt parameter is\nnot an OCTET STRING type this can lead to invalid or NULL pointer\ndereference.\n\nExploiting this issue requires a user or application to process\na maliciously crafted PKCS#12 file. It is uncommon to accept untrusted\nPKCS#12 files in applications as they are usually used to store private\nkeys which are trusted by definition.
