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-2018-20588 in the wild and no public exploit code.\n\nAffected product: Otfcc Project Otfcc. 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-2018-20588/ (Markdown: https://insights.sbomify.com/CVE-2018-20588/index.md)","id":"CVE-2018-20588","markdown":"https://insights.sbomify.com/CVE-2018-20588/index.md","name":"CVE-2018-20588","record":{"aliases":["GHSA-ph84-9xrw-hw7p"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenType font compiler","requires_auth":"none","summary":"A buffer over-read in the otfcc library allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"otfcc","vendor":"otfcc_project"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"lib/support/unicodeconv/unicodeconv.c in libotfcc.a in otfcc v0.10.3-alpha has a buffer over-read.","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-2018-20588","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"otfcc_project:otfcc","products":["otfcc_project:otfcc"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-20589"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2018-20587"},"products":["n/a"],"published":"2018-12-30","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2022-33047","kev_date_added":null,"published":"2022-07-06"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35040","kev_date_added":null,"published":"2022-10-14"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35041","kev_date_added":null,"published":"2022-10-14"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35042","kev_date_added":null,"published":"2022-10-14"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35043","kev_date_added":null,"published":"2022-10-14"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35044","kev_date_added":null,"published":"2022-10-14"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2022-35045","kev_date_added":null,"published":"2022-10-14"}],"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 buffer over-read in the otfcc library allows attackers to cause denial of service or disclose sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2018-20588/"}
