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-2020-5496 in the wild and no public exploit code.\n\nAffected product: Opensuse Leap. 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-2020-5496/ (Markdown: https://insights.sbomify.com/CVE-2020-5496/index.md)","id":"CVE-2020-5496","markdown":"https://insights.sbomify.com/CVE-2020-5496/index.md","name":"CVE-2020-5496","record":{"aliases":["DEBIAN-CVE-2020-5496","GHSA-v4hc-3q2q-94jp","UBUNTU-CVE-2020-5496"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"FontForge font editor","requires_auth":"none","summary":"A heap-based buffer overflow in FontForge allows attackers to execute arbitrary code or cause a denial of service via crafted font files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fontforge","vendor":"fontforge"},{"product":"leap","vendor":"opensuse"}],"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-787","name":"Out-of-bounds Write"}],"description":"FontForge 20190801 has a heap-based buffer overflow in the Type2NotDefSplines() function in splinesave.c.","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":"Memory corruption in n/a","id":"CVE-2020-5496","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"opensuse:leap","products":["opensuse:leap"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"XSS in MITREid Connect","id":"CVE-2020-5497"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2020-5495"},"products":["n/a"],"published":"2020-01-03","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2019-15785","kev_date_added":null,"published":"2019-08-29"},{"cvss_score":8.8,"headline":"FontForge SFD File Parsing Use-After-Free Remote Code Execution Vulnerability","id":"CVE-2025-15269","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":8.8,"headline":"FontForge SFD File Parsing Improper Validation of Array Index Remote Code Execution Vulnerability","id":"CVE-2025-15270","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":8.8,"headline":"FontForge SFD File Parsing Improper Validation of Array Index Remote Code Execution Vulnerability","id":"CVE-2025-15271","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":8.8,"headline":"FontForge SFD File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-15272","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":8.8,"headline":"FontForge PFB File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-15273","kev_date_added":null,"published":"2025-12-31"},{"cvss_score":8.8,"headline":"FontForge SFD File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability","id":"CVE-2025-15274","kev_date_added":null,"published":"2025-12-31"}],"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":"A heap-based buffer overflow in FontForge allows attackers to execute arbitrary code or cause a denial of service via crafted font files.","url":"https://insights.sbomify.com/CVE-2020-5496/"}
