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-2018-20316 in the wild and no public exploit code.\n\nAffected product: Foxitsoftware Phantompdf. 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-2018-20316/ (Markdown: https://insights.sbomify.com/CVE-2018-20316/index.md)","id":"CVE-2018-20316","markdown":"https://insights.sbomify.com/CVE-2018-20316/index.md","name":"CVE-2018-20316","record":{"aliases":["GHSA-3f3f-hqx2-w523"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PDF reader","requires_auth":"none","summary":"A race condition in Foxit Reader and PhantomPDF allows attackers to trigger stack-based buffer overflows or out-of-bounds reads, potentially leading to code execution or crashes.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"phantompdf","vendor":"foxitsoftware"},{"product":"reader","vendor":"foxitsoftware"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Foxit Reader before 9.5, and PhantomPDF before 8.3.10 and 9.x before 9.5, has a proxyDoAction race condition that can cause a stack-based buffer overflow or an out-of-bounds read, a different issue than CVE-2018-20310 because of a different opcode.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Race condition in n/a","id":"CVE-2018-20316","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"foxitsoftware:phantompdf","products":["foxitsoftware:phantompdf","foxitsoftware:reader"],"type":"race_condition","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"XML external entity in n/a","id":"CVE-2018-20318"},"packages":[],"prev":{"headline":"Race condition in n/a","id":"CVE-2018-20315"},"products":["n/a"],"published":"2021-01-07","related":[{"cvss_score":9.8,"headline":"An issue was discovered in Foxit PhantomPDF before 8.3.6.","id":"CVE-2018-21242","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2018-21244","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-20825","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2019-20827","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-20830","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-13804","kev_date_added":null,"published":"2020-06-04"},{"cvss_score":9.8,"headline":"Security feature bypass in n/a","id":"CVE-2020-13805","kev_date_added":null,"published":"2020-06-04"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A race condition in Foxit Reader and PhantomPDF allows attackers to trigger stack-based buffer overflows or out-of-bounds reads, potentially leading to code execution or crashes.","url":"https://insights.sbomify.com/CVE-2018-20316/"}
