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-2011-1956 exists.\n\nAffected product: Wireshark Wireshark. 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-2011-1956/ (Markdown: https://insights.sbomify.com/CVE-2011-1956/index.md)","id":"CVE-2011-1956","markdown":"https://insights.sbomify.com/CVE-2011-1956/index.md","name":"CVE-2011-1956","record":{"aliases":["DEBIAN-CVE-2011-1956","GHSA-hqw9-f827-9xw8"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Wireshark network analyzer","requires_auth":"none","summary":"Remote attackers can crash Wireshark via arbitrary TCP traffic due to a NULL pointer dereference in the bytes_repr_len function.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"wireshark","vendor":"wireshark"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"The bytes_repr_len function in Wireshark 1.4.5 uses an incorrect pointer argument, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via arbitrary TCP traffic.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-06-17","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-06-17","kind":"exploitdb","ref":"35873","stars":null,"title":"Wireshark 1.4.5 - 'bytes_repr_len()' Null Pointer Dereference Denial of Service"}],"tier":"weaponised"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2011-1956","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"wireshark:wireshark","products":["wireshark:wireshark"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":8,"next":{"headline":"Denial of service in n/a","id":"CVE-2011-1957"},"packages":[],"prev":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2011-1955"},"products":["n/a"],"published":"2011-06-06","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-0444","kev_date_added":null,"published":"2011-01-12"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-2994","kev_date_added":null,"published":"2010-08-13"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2010-2995","kev_date_added":null,"published":"2010-08-13"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2009-1266","kev_date_added":null,"published":"2009-04-21"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-1210","kev_date_added":null,"published":"2009-04-01"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-3146","kev_date_added":null,"published":"2008-09-02"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-6112","kev_date_added":null,"published":"2007-11-23"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can crash Wireshark via arbitrary TCP traffic due to a NULL pointer dereference in the bytes_repr_len function.","url":"https://insights.sbomify.com/CVE-2011-1956/"}
