An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2007-0021 exists.\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-2007-0021/ (Markdown: https://insights.sbomify.com/CVE-2007-0021/index.md)","id":"CVE-2007-0021","markdown":"https://insights.sbomify.com/CVE-2007-0021/index.md","name":"CVE-2007-0021","record":{"aliases":["GHSA-4c3v-jr8f-g5h4"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Apple iChat","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute arbitrary code via format string specifiers in aim:// URIs in Apple iChat.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ichat","vendor":"apple"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[],"description":"Format string vulnerability in Apple iChat 3.1.6 allows remote attackers to cause a denial of service (null pointer dereference and application crash) and possibly execute arbitrary code via format string specifiers in an aim:// URI.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2007-01-21","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2007-01-21","kind":"exploitdb","ref":"3166","stars":null,"title":"Apple iChat 3.1.6 441 - 'aim://' URL Handler Format String (PoC)"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2007-0021","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2007"},"n_packages":0,"n_references":11,"next":{"headline":"Path traversal in n/a","id":"CVE-2007-0022"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2007-0020"},"products":["n/a"],"published":"2007-01-23","related":[{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2007-0614","kev_date_added":null,"published":"2007-01-31"},{"cvss_score":7.5,"headline":"Code injection in n/a","id":"CVE-2004-0873","kev_date_added":null,"published":"2004-09-24"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2007-3746","kev_date_added":null,"published":"2007-08-03"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2007-3747","kev_date_added":null,"published":"2007-08-03"},{"cvss_score":5.4,"headline":"Memory corruption in n/a","id":"CVE-2007-3748","kev_date_added":null,"published":"2007-08-03"},{"cvss_score":5,"headline":"Denial of service in n/a","id":"CVE-2007-0613","kev_date_added":null,"published":"2007-01-31"}],"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":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service or execute arbitrary code via format string specifiers in aim:// URIs in Apple iChat.","url":"https://insights.sbomify.com/CVE-2007-0021/"}
