An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-0767 in the wild and no public exploit code.\n\nAffected product: Mozilla Firefox. 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-2023-0767/ (Markdown: https://insights.sbomify.com/CVE-2023-0767/index.md)","id":"CVE-2023-0767","markdown":"https://insights.sbomify.com/CVE-2023-0767/index.md","name":"CVE-2023-0767","record":{"aliases":["ALSA-2023:1252","ALSA-2023:1368","CLSA-2023-1681327540","CLSA-2023-1681327693","CLSA-2023-1681328662","CLSA-2023-1681739907","CLSA-2023-1681744375","DEBIAN-CVE-2023-0767","DSA-5353-1","GHSA-687w-wqw8-qq8j","RHSA-2023:1252","RHSA-2023:1332","RHSA-2023:1365","RHSA-2023:1366","RHSA-2023:1368","RHSA-2023:1369","RHSA-2023:1370","RHSA-2023:1406","RHSA-2023:1436","RLSA-2023:1252","RLSA-2023:1368","SUSE-SU-2023:0434-1","SUSE-SU-2023:0443-1","SUSE-SU-2023:0468-1","UBUNTU-CVE-2023-0767","USN-5892-1","USN-5892-2"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Mozilla Firefox","requires_auth":"none","summary":"An attacker can achieve arbitrary memory writes and potential code execution by crafting a malicious PKCS 12 certificate bundle.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mozilla","cpe":[{"product":"firefox","vendor":"mozilla"},{"product":"firefox_esr","vendor":"mozilla"},{"product":"thunderbird","vendor":"mozilla"}],"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":[],"description":"An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled.
