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-2021-39858 in the wild and no public exploit code.\n\nAffected product: Adobe Acrobat. 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-2021-39858/ (Markdown: https://insights.sbomify.com/CVE-2021-39858/index.md)","id":"CVE-2021-39858","markdown":"https://insights.sbomify.com/CVE-2021-39858/index.md","name":"CVE-2021-39858","record":{"aliases":["GHSA-vf6x-fv96-2mwx"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"An out-of-bounds read in Adobe Acrobat allows attackers to disclose arbitrary memory information by tricking users into opening a malicious file.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"adobe","cpe":[{"product":"acrobat","vendor":"adobe"},{"product":"acrobat_2017","vendor":"adobe"},{"product":"acrobat_dc","vendor":"adobe"},{"product":"acrobat_reader","vendor":"adobe"},{"product":"acrobat_reader_2017","vendor":"adobe"},{"product":"acrobat_reader_dc","vendor":"adobe"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Acrobat Reader DC versions 2021.005.20060 (and earlier), 2020.004.30006 (and earlier) and 2017.011.30199 (and earlier) are affected by an out-of-bounds read vulnerability that could lead to disclosure of arbitrary memory information in the context of the current user.
