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-2003-0431 in the wild and no public exploit code.\n\nAffected product: Ethereal Group Ethereal. 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-2003-0431/ (Markdown: https://insights.sbomify.com/CVE-2003-0431/index.md)","id":"CVE-2003-0431","markdown":"https://insights.sbomify.com/CVE-2003-0431/index.md","name":"CVE-2003-0431","record":{"aliases":["GHSA-hrr2-5hxg-8fpx"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Ethereal network analyzer","requires_auth":"none","summary":"A flaw in Ethereal's string handling function can cause a denial of service when processing zero-length buffers.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ethereal","vendor":"ethereal_group"}],"cvss":{"score":10,"severity":"critical","source":"nvd","vector":"AV:N/AC:L/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[],"description":"The tvb_get_nstringz0 function in Ethereal 0.9.12 and earlier does not properly handle a zero-length buffer size, with unknown consequences.","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":"Denial of service in n/a","id":"CVE-2003-0431","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"ethereal_group:ethereal","products":["ethereal_group:ethereal"],"type":"denial_of_service","year":"2003"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2003-0432"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2003-0430"},"products":["n/a"],"published":"2003-06-18","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2006-3628","kev_date_added":null,"published":"2006-07-18"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-3632","kev_date_added":null,"published":"2006-07-18"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2006-1932","kev_date_added":null,"published":"2006-04-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2005-3184","kev_date_added":null,"published":"2005-10-20"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0507","kev_date_added":null,"published":"2004-06-03"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2003-0432","kev_date_added":null,"published":"2003-06-18"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-08","vendors":["n/a"]},"summary":"A flaw in Ethereal's string handling function can cause a denial of service when processing zero-length buffers.","url":"https://insights.sbomify.com/CVE-2003-0431/"}
