It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-2663 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-2023-2663/ (Markdown: https://insights.sbomify.com/CVE-2023-2663/index.md)","id":"CVE-2023-2663","markdown":"https://insights.sbomify.com/CVE-2023-2663/index.md","name":"CVE-2023-2663","record":{"aliases":["CVE-2023-31554","GHSA-8wrw-hcvf-r5f8","UBUNTU-CVE-2023-2663"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"PDF viewer","requires_auth":"none","summary":"An attacker can cause a stack overflow and crash the application by providing a PDF with a malicious object loop in the page label tree.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GandC","cpe":[{"product":"xpdf","vendor":"xpdfreader"}],"cvss":{"score":2.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-674","name":"Uncontrolled Recursion"}],"description":"In Xpdf 4.04 (and earlier), a PDF object loop in the page label tree leads to infinite recursion and a stack 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":"Stack overflow in Xpdf 4.04 due to object loop in PDF page label tree","id":"CVE-2023-2663","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xpdfreader:xpdf","products":["xpdfreader:xpdf"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Stack overflow in Xpdf 4.04 due to object loop in PDF embedded file tree","id":"CVE-2023-2664"},"packages":[],"prev":{"headline":"Divide-by-zero in Xpdf 4.04 due to bad color space object","id":"CVE-2023-2662"},"products":["Xpdf"],"published":"2023-05-11","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-24","vendors":["Xpdf"]},"summary":"An attacker can cause a stack overflow and crash the application by providing a PDF with a malicious object loop in the page label tree.","url":"https://insights.sbomify.com/CVE-2023-2663/"}
