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-2020-6623 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-6623/ (Markdown: https://insights.sbomify.com/CVE-2020-6623/index.md)","id":"CVE-2020-6623","markdown":"https://insights.sbomify.com/CVE-2020-6623/index.md","name":"CVE-2020-6623","record":{"aliases":["GHSA-vv98-vgrj-89fm","UBUNTU-CVE-2020-6623"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"stb TrueType library","requires_auth":"none","summary":"An assertion failure in the stb_truetype library allows attackers to cause a denial of service via crafted TrueType fonts.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"stb_truetype.h","vendor":"nothings"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"stb stb_truetype.h through 1.22 has an assertion failure in stbtt__cff_get_index.","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":"Denial of service in n/a","id":"CVE-2020-6623","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2020-6624"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2020-6622"},"products":["n/a"],"published":"2020-01-08","related":[{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2020-6617","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6618","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":8.8,"headline":"Denial of service in n/a","id":"CVE-2020-6619","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6620","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6621","kev_date_added":null,"published":"2020-01-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-6622","kev_date_added":null,"published":"2020-01-08"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"An assertion failure in the stb_truetype library allows attackers to cause a denial of service via crafted TrueType fonts.","url":"https://insights.sbomify.com/CVE-2020-6623/"}
