An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-17821 in the wild and no public exploit code.\n\nAffected product: Apple Safari. 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-2017-17821/ (Markdown: https://insights.sbomify.com/CVE-2017-17821/index.md)","id":"CVE-2017-17821","markdown":"https://insights.sbomify.com/CVE-2017-17821/index.md","name":"CVE-2017-17821","record":{"aliases":["DEBIAN-CVE-2017-17821","GHSA-353g-x49j-hjg7","UBUNTU-CVE-2017-17821"],"analysis":{"component_type":"browser","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WebKit browser engine","requires_auth":"none","summary":"Remote attackers can cause denial of service or potentially execute code via a buffer overflow in WebKit's FastBitVector implementation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"safari","vendor":"apple"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"WTF/wtf/FastBitVector.h in WebKit, as distributed in Safari Technology Preview Release 46, allows remote attackers to cause a denial of service (buffer overflow) or possibly have unspecified other impact because it calls the FastBitVectorWordOwner::resizeSlow function (in WTF/wtf/FastBitVector.cpp) for a purpose other than initializing a bitvector size, and resizeSlow mishandles cases where the old array length is greater than the new array length.","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-2017-17821","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"apple:safari","products":["apple:safari"],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in n/a","id":"CVE-2017-17822"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2017-17820"},"products":["n/a"],"published":"2017-12-21","related":[{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2015-5780","kev_date_added":null,"published":"2015-10-09"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2014-1300","kev_date_added":null,"published":"2014-03-26"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-1303","kev_date_added":null,"published":"2014-03-26"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2010-1120","kev_date_added":null,"published":"2010-03-25"},{"cvss_score":10,"headline":"Cross-site scripting in n/a","id":"CVE-2009-0137","kev_date_added":null,"published":"2009-02-13"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2008-2303","kev_date_added":null,"published":"2008-07-14"},{"cvss_score":10,"headline":"Information disclosure in n/a","id":"CVE-2007-2843","kev_date_added":null,"published":"2007-05-24"}],"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":"Remote attackers can cause denial of service or potentially execute code via a buffer overflow in WebKit's FastBitVector implementation.","url":"https://insights.sbomify.com/CVE-2017-17821/"}
