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-2009-1856 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-2009-1856/ (Markdown: https://insights.sbomify.com/CVE-2009-1856/index.md)","id":"CVE-2009-1856","markdown":"https://insights.sbomify.com/CVE-2009-1856/index.md","name":"CVE-2009-1856","record":{"aliases":["GHSA-888m-whhh-898w"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Adobe Reader Acrobat","requires_auth":"none","summary":"Attackers can execute arbitrary code or cause denial of service via a malicious PDF file exploiting an integer overflow in Adobe Reader and Acrobat.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"acrobat","vendor":"adobe"},{"product":"acrobat_reader","vendor":"adobe"}],"cvss":{"score":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Integer overflow in Adobe Reader 7 and Acrobat 7 before 7.1.3, Adobe Reader 8 and Acrobat 8 before 8.1.6, and Adobe Reader 9 and Acrobat 9 before 9.1.2 allows attackers to cause a denial of service or possibly execute arbitrary code via a PDF file containing unspecified parameters to the FlateDecode filter, which triggers a heap-based buffer overflow.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2009-1856","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"adobe:acrobat","products":["adobe:acrobat","adobe:acrobat_reader"],"type":"integer_overflow","year":"2009"},"n_packages":0,"n_references":17,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-1857"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2009-1855"},"products":["n/a"],"published":"2009-06-11","related":[{"cvss_score":9.6,"headline":"Adobe Acrobat and Reader Use-After-Free","id":"CVE-2021-28550","kev_date_added":"2021-11-03","published":"2021-09-02"},{"cvss_score":8.8,"headline":"Adobe Acrobat and Reader Heap-based Buffer Overflow","id":"CVE-2021-21017","kev_date_added":"2021-11-03","published":"2021-02-11"},{"cvss_score":8.8,"headline":"Adobe Reader and Acrobat Sandbox Bypass","id":"CVE-2014-0546","kev_date_added":"2022-05-25","published":"2014-08-12"},{"cvss_score":8.8,"headline":"Adobe Reader and Acrobat Use-After-Free","id":"CVE-2014-0496","kev_date_added":"2022-03-03","published":"2014-01-15"},{"cvss_score":8.8,"headline":"Adobe Reader and Acrobat Memory Corruption","id":"CVE-2013-3346","kev_date_added":"2022-03-03","published":"2013-08-30"},{"cvss_score":8.8,"headline":"Adobe Reader and Acrobat Arbitrary Integer Overflow","id":"CVE-2013-2729","kev_date_added":"2022-03-28","published":"2013-05-16"},{"cvss_score":8.8,"headline":"Adobe Reader and Acrobat Universal 3D Memory Corruption","id":"CVE-2011-2462","kev_date_added":"2022-06-08","published":"2011-12-07"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Attackers can execute arbitrary code or cause denial of service via a malicious PDF file exploiting an integer overflow in Adobe Reader and Acrobat.","url":"https://insights.sbomify.com/CVE-2009-1856/"}
