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-2003-0540 exists.\n\nAffected product: Conectiva Linux. 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-2003-0540/ (Markdown: https://insights.sbomify.com/CVE-2003-0540/index.md)","id":"CVE-2003-0540","markdown":"https://insights.sbomify.com/CVE-2003-0540/index.md","name":"CVE-2003-0540","record":{"aliases":["DEBIAN-CVE-2003-0540","GHSA-cgrr-3rc7-3h4r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Postfix mail server","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Postfix by sending malformed email addresses containing specific strings, locking up the queue manager or SMTP listener.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"linux","vendor":"conectiva"},{"product":"postfix","vendor":"wietse_venema"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[],"description":"The address parser code in Postfix 1.1.12 and earlier allows remote attackers to cause a denial of service (lock) via (1) a malformed envelope address to a local host that would generate a bounce and contains the \".!\" string in the MAIL FROM or Errors-To headers, which causes nqmgr to lock up, or (2) via a valid MAIL FROM with a RCPT TO containing a \".!\" string, which causes an instance of the SMTP listener to lock up.","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2003-08-04","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2003-08-04","kind":"exploitdb","ref":"22981","stars":null,"title":"Postfix 1.1.x - Denial of Service (1)"},{"date":"2003-08-04","kind":"exploitdb","ref":"22982","stars":null,"title":"Postfix 1.1.x - Denial of Service (2)"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2003-0540","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"conectiva:linux","products":["conectiva:linux"],"type":"denial_of_service","year":"2003"},"n_packages":0,"n_references":13,"next":{"headline":"Null dereference in n/a","id":"CVE-2003-0541"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2003-0539"},"products":["n/a"],"published":"2003-08-05","related":[{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2005-3625","kev_date_added":null,"published":"2006-01-06"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0882","kev_date_added":null,"published":"2004-11-19"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0902","kev_date_added":null,"published":"2004-09-24"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0903","kev_date_added":null,"published":"2004-09-24"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-0904","kev_date_added":null,"published":"2004-09-24"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2000-0747","kev_date_added":null,"published":"2004-09-01"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0557","kev_date_added":null,"published":"2004-08-02"}],"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":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can cause a denial of service in Postfix by sending malformed email addresses containing specific strings, locking up the queue manager or SMTP listener.","url":"https://insights.sbomify.com/CVE-2003-0540/"}
