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-2021-36493 in the wild and no public exploit code.\n\nAffected product: Xpdfreader Xpdf. 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-2021-36493/ (Markdown: https://insights.sbomify.com/CVE-2021-36493/index.md)","id":"CVE-2021-36493","markdown":"https://insights.sbomify.com/CVE-2021-36493/index.md","name":"CVE-2021-36493","record":{"aliases":["GHSA-32jj-wp9g-2g8g","UBUNTU-CVE-2021-36493"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF processing library","requires_auth":"none","summary":"Attackers can crash the application via a crafted command due to a buffer overflow in pdfimages.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xpdf","vendor":"xpdfreader"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Buffer Overflow vulnerability in pdfimages in xpdf 4.03 allows attackers to crash the application via crafted command.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in n/a","id":"CVE-2021-36493","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xpdfreader:xpdf","products":["xpdfreader:xpdf"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2021-36503"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2021-36489"},"products":["n/a"],"published":"2023-02-03","related":[{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2022-38928","kev_date_added":null,"published":"2022-09-21"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2022-38222","kev_date_added":null,"published":"2022-08-15"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-33108","kev_date_added":null,"published":"2022-06-28"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2022-30524","kev_date_added":null,"published":"2022-05-09"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2020-24996","kev_date_added":null,"published":"2020-09-03"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2020-24999","kev_date_added":null,"published":"2020-09-03"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2019-9877","kev_date_added":null,"published":"2019-03-19"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-03-27","vendors":["n/a"]},"summary":"Attackers can crash the application via a crafted command due to a buffer overflow in pdfimages.","url":"https://insights.sbomify.com/CVE-2021-36493/"}
