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-2011-1764 in the wild and no public exploit code.\n\nAffected product: Exim Exim. 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-2011-1764/ (Markdown: https://insights.sbomify.com/CVE-2011-1764/index.md)","id":"CVE-2011-1764","markdown":"https://insights.sbomify.com/CVE-2011-1764/index.md","name":"CVE-2011-1764","record":{"aliases":["DEBIAN-CVE-2011-1764","DSA-2232-1","GHSA-mhvp-9557-5gxf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Exim mail server","requires_auth":"none","summary":"Remote attackers can execute arbitrary code or crash the Exim mail server via format string vulnerabilities in DKIM logging.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"exim","vendor":"exim"}],"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":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"Format string vulnerability in the dkim_exim_verify_finish function in src/dkim.c in Exim before 4.76 might allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via format string specifiers in data used in DKIM logging, as demonstrated by an identity field containing a % (percent) character.","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":"Other in n/a","id":"CVE-2011-1764","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exim:exim","products":["exim:exim"],"type":"other","year":"2011"},"n_packages":0,"n_references":7,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2011-1765"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2011-1763"},"products":["n/a"],"published":"2011-10-05","related":[{"cvss_score":9.8,"headline":"Use after free in Exim","id":"CVE-2026-45185","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9.8,"headline":"Exim AUTH Out-Of-Bounds Write Remote Code Execution Vulnerability","id":"CVE-2023-42115","kev_date_added":null,"published":"2024-05-03"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28017","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-28018","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2020-28020","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28022","kev_date_added":null,"published":"2021-05-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-28024","kev_date_added":null,"published":"2021-05-06"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code or crash the Exim mail server via format string vulnerabilities in DKIM logging.","url":"https://insights.sbomify.com/CVE-2011-1764/"}
