Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-32559 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pywin32 (PyPI): affected all versions; fixed in 301\n- pywin32 (PyPI): affected all versions; fixed in 301\n- pywin32 (PyPI): affected all versions; fixed in 301\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-2021-32559/ (Markdown: https://insights.sbomify.com/CVE-2021-32559/index.md)","id":"CVE-2021-32559","markdown":"https://insights.sbomify.com/CVE-2021-32559/index.md","name":"CVE-2021-32559","record":{"aliases":["GHSA-hwfp-hg2m-9vr2","PYSEC-2021-112"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Python Windows extensions","requires_auth":"low_privilege","summary":"An integer overflow in pywin32 allows attackers to crash the process by adding large access control entries to an ACL.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pywin32","vendor":"mhammond"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow exists in pywin32 prior to version b301 when adding an access control entry (ACE) to an access control list (ACL) that would cause the size to be greater than 65535 bytes.
