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: There is no known exploitation of CVE-2021-31844 in the wild and no public exploit code.\n\nAffected product: McAfee,LLC McAfee Data Loss Prevention (DLP) Endpoint for Windows. 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-2021-31844/ (Markdown: https://insights.sbomify.com/CVE-2021-31844/index.md)","id":"CVE-2021-31844","markdown":"https://insights.sbomify.com/CVE-2021-31844/index.md","name":"CVE-2021-31844","record":{"aliases":["GHSA-88gm-mqfx-w7ch"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"McAfee DLP Endpoint","requires_auth":"low_privilege","summary":"A local attacker can execute arbitrary code with elevated privileges by placing a malicious Ami Pro file on the system to trigger a buffer overflow in McAfee DLP Endpoint.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"trellix","cpe":[{"product":"data_loss_prevention_endpoint","vendor":"mcafee"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.200 allows a local attacker to execute arbitrary code with elevated privileges through placing carefully constructed Ami Pro (.sam) files onto the local system and triggering a DLP Endpoint scan through accessing a file.
