An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2018-11646 exists.\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-2018-11646/ (Markdown: https://insights.sbomify.com/CVE-2018-11646/index.md)","id":"CVE-2018-11646","markdown":"https://insights.sbomify.com/CVE-2018-11646/index.md","name":"CVE-2018-11646","record":{"aliases":["DEBIAN-CVE-2018-11646","GHSA-q2c8-4vmf-78h5","UBUNTU-CVE-2018-11646"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WebKitGTK library","requires_auth":"none","summary":"An attacker can cause an application crash in WebKitGTK by triggering a null pointer dereference in the favicon database handling.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"webkitgtk\\+","vendor":"webkitgtk"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"webkitFaviconDatabaseSetIconForPageURL and webkitFaviconDatabaseSetIconURLForPageURL in UIProcess/API/glib/WebKitFaviconDatabase.cpp in WebKit, as used in WebKitGTK+ through 2.21.3, mishandle an unset pageURL, leading to an application crash.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2018-06-03","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2018-06-03","kind":"metasploit","ref":"auxiliary/dos/http/webkitplus","stars":null,"title":"WebKitGTK+ WebKitFaviconDatabase DoS"},{"date":"2018-06-05","kind":"exploitdb","ref":"44842","stars":null,"title":"WebKitGTK+ \u003c 2.21.3 - Crash (PoC)"},{"date":"2018-06-11","kind":"exploitdb","ref":"44876","stars":null,"title":"WebKitGTK+ \u003c 2.21.3 - 'WebKitFaviconDatabase' Denial of Service (Metasploit)"}],"tier":"weaponised"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2018-11646","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"webkitgtk:webkitgtk\\+","products":["webkitgtk:webkitgtk\\+"],"type":"null_dereference","year":"2018"},"n_packages":0,"n_references":5,"next":{"headline":"oauth2orize-fprm XSS vulnerability","id":"CVE-2018-11647"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2018-11645"},"products":["n/a"],"published":"2018-06-01","related":[{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2017-1000121","kev_date_added":null,"published":"2017-11-01"},{"cvss_score":7.5,"headline":"Security feature bypass in n/a","id":"CVE-2018-11712","kev_date_added":null,"published":"2018-06-04"},{"cvss_score":5.3,"headline":"Denial of service in n/a","id":"CVE-2017-1000122","kev_date_added":null,"published":"2017-11-01"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can cause an application crash in WebKitGTK by triggering a null pointer dereference in the favicon database handling.","url":"https://insights.sbomify.com/CVE-2018-11646/"}
