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-2021-45481 in the wild and no public exploit code.\n\nAffected product: Webkitgtk Webkitgtk. 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-2021-45481/ (Markdown: https://insights.sbomify.com/CVE-2021-45481/index.md)","id":"CVE-2021-45481","markdown":"https://insights.sbomify.com/CVE-2021-45481/index.md","name":"CVE-2021-45481","record":{"aliases":["DEBIAN-CVE-2021-45481","GHSA-p53f-pm5m-wpj7","UBUNTU-CVE-2021-45481"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WebKitGTK rendering library","requires_auth":"none","summary":"Incorrect memory allocation in WebKitGTK causes a segmentation violation and application crash, leading to denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"webkitgtk","vendor":"webkitgtk"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-401","name":"Missing Release of Memory after Effective Lifetime"}],"description":"In WebKitGTK before 2.32.4, there is incorrect memory allocation in WebCore::ImageBufferCairoImageSurfaceBackend::create, leading to a segmentation violation and application crash, a different vulnerability than CVE-2021-30889.","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-2021-45481","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"webkitgtk:webkitgtk","products":["webkitgtk:webkitgtk"],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Use after free in n/a","id":"CVE-2021-45482"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-45480"},"products":["n/a"],"published":"2021-12-25","related":[{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2023-25360","kev_date_added":null,"published":"2023-03-02"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2023-25361","kev_date_added":null,"published":"2023-03-02"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2023-25362","kev_date_added":null,"published":"2023-03-02"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2023-25363","kev_date_added":null,"published":"2023-03-02"},{"cvss_score":8.8,"headline":"Use after free in Webkit","id":"CVE-2021-21806","kev_date_added":null,"published":"2021-07-08"},{"cvss_score":8.8,"headline":"Use after free in Webkit","id":"CVE-2020-13558","kev_date_added":null,"published":"2021-03-03"},{"cvss_score":8.8,"headline":"Use after free in Webkit","id":"CVE-2020-13543","kev_date_added":null,"published":"2020-12-03"}],"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":"Incorrect memory allocation in WebKitGTK causes a segmentation violation and application crash, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2021-45481/"}
