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-2018-1000807 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pyopenssl (PyPI): affected all versions; fixed in 17.5.0\n- pyopenssl (PyPI): affected all versions; fixed in 17.5.0\n- pyopenssl (PyPI): affected all versions; fixed in 17.5.0\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-2018-1000807/ (Markdown: https://insights.sbomify.com/CVE-2018-1000807/index.md)","id":"CVE-2018-1000807","markdown":"https://insights.sbomify.com/CVE-2018-1000807/index.md","name":"CVE-2018-1000807","record":{"aliases":["ALPINE-CVE-2018-1000807","DEBIAN-CVE-2018-1000807","GHSA-p28m-34f6-967q","PYSEC-2018-23","SUSE-SU-2024:3749-1","UBUNTU-CVE-2018-1000807"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python cryptography library","requires_auth":"none","summary":"A use-after-free flaw in pyopenssl allows attackers to cause denial of service or execute arbitrary code via crafted X509 objects.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"pyopenssl","vendor":"pyopenssl"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"openstack","vendor":"redhat"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"Python Cryptographic Authority pyopenssl version prior to version 17.5.0 contains a CWE-416: Use After Free vulnerability in X509 object handling that can result in Use after free can lead to possible denial of service or remote code execution..
