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-2018-19876 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-2018-19876/ (Markdown: https://insights.sbomify.com/CVE-2018-19876/index.md)","id":"CVE-2018-19876","markdown":"https://insights.sbomify.com/CVE-2018-19876/index.md","name":"CVE-2018-19876","record":{"aliases":["ALPINE-CVE-2018-19876","DEBIAN-CVE-2018-19876","GHSA-m5xr-7jg3-vh46","JLSEC-2025-14"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cairo graphics library","requires_auth":"none","summary":"An attacker can cause a denial of service in applications using Cairo by triggering a memory management error that leads to an application crash.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cairo","vendor":"cairographics"}],"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-416","name":"Use After Free"}],"description":"cairo 1.16.0, in cairo_ft_apply_variations() in cairo-ft-font.c, would free memory using a free function incompatible with WebKit's fastMalloc, leading to an application crash with a \"free(): invalid pointer\" error.","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":"Use after free in n/a","id":"CVE-2018-19876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2018"},"n_packages":0,"n_references":2,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-19877"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2018-19873"},"products":["n/a"],"published":"2018-12-05","related":[{"cvss_score":7.8,"headline":"Memory corruption in cairo","id":"CVE-2020-35492","kev_date_added":null,"published":"2021-03-18"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-9814","kev_date_added":null,"published":"2017-07-14"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-3190","kev_date_added":null,"published":"2016-04-21"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2019-6461","kev_date_added":null,"published":"2019-01-16"},{"cvss_score":6.5,"headline":"Denial of service in n/a","id":"CVE-2019-6462","kev_date_added":null,"published":"2019-01-16"},{"cvss_score":6.5,"headline":"Memory corruption in n/a","id":"CVE-2018-18064","kev_date_added":null,"published":"2018-10-08"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-15","vendors":["n/a"]},"summary":"An attacker can cause a denial of service in applications using Cairo by triggering a memory management error that leads to an application crash.","url":"https://insights.sbomify.com/CVE-2018-19876/"}
