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-2012-5643 in the wild and no public exploit code.\n\nAffected product: Squid-Cache Squid. 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-2012-5643/ (Markdown: https://insights.sbomify.com/CVE-2012-5643/index.md)","id":"CVE-2012-5643","markdown":"https://insights.sbomify.com/CVE-2012-5643/index.md","name":"CVE-2012-5643","record":{"aliases":["DEBIAN-CVE-2012-5643","GHSA-pq8w-rcmc-8xgj","RHSA-2013:0505"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Squid proxy server","requires_auth":"none","summary":"Remote attackers can cause a denial of service in Squid proxy servers via crafted HTTP requests leading to memory exhaustion.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"squid","vendor":"squid-cache"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Multiple memory leaks in tools/cachemgr.cc in cachemgr.cgi in Squid 2.x and 3.x before 3.1.22, 3.2.x before 3.2.4, and 3.3.x before 3.3.0.2 allow remote attackers to cause a denial of service (memory consumption) via (1) invalid Content-Length headers, (2) long POST requests, or (3) crafted authentication credentials.","ecosystems":["Red Hat:enterprise_linux:6::server","Red Hat:enterprise_linux:6::workstation"],"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-2012-5643","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"squid-cache:squid","products":["squid-cache:squid"],"type":"denial_of_service","year":"2012"},"n_packages":4,"n_references":20,"next":{"headline":"Information disclosure in libuser","id":"CVE-2012-5644"},"packages":[{"ecosystem":"Red Hat:enterprise_linux:6::server","fixed":["7:3.1.10-16.el6"],"introduced":["0"],"last_affected":[],"package":"squid","purl":"pkg:rpm/redhat/squid","source":"RHSA-2013:0505"},{"ecosystem":"Red Hat:enterprise_linux:6::server","fixed":["7:3.1.10-16.el6"],"introduced":["0"],"last_affected":[],"package":"squid-debuginfo","purl":"pkg:rpm/redhat/squid-debuginfo","source":"RHSA-2013:0505"},{"ecosystem":"Red Hat:enterprise_linux:6::workstation","fixed":["7:3.1.10-16.el6"],"introduced":["0"],"last_affected":[],"package":"squid","purl":"pkg:rpm/redhat/squid","source":"RHSA-2013:0505"},{"ecosystem":"Red Hat:enterprise_linux:6::workstation","fixed":["7:3.1.10-16.el6"],"introduced":["0"],"last_affected":[],"package":"squid-debuginfo","purl":"pkg:rpm/redhat/squid-debuginfo","source":"RHSA-2013:0505"}],"prev":{"headline":"Command injection in n/a","id":"CVE-2012-5642"},"products":["n/a"],"published":"2012-12-20","related":[{"cvss_score":10,"headline":"Squid vulnerable to information disclosure via authentication credential leakage in error handling","id":"CVE-2025-62168","kev_date_added":null,"published":"2025-10-17"},{"cvss_score":9.3,"headline":"Squid's URN Handling can lead to Buffer Overflow","id":"CVE-2025-54574","kev_date_added":null,"published":"2025-08-01"},{"cvss_score":9.2,"headline":"Squid vulnerable to Denial of Service in ICP Request handling","id":"CVE-2026-33526","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":8.7,"headline":"Squid has Denial of Service in ICP Response handling","id":"CVE-2026-32748","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":8.6,"headline":"SQUID-2023:10 Denial of Service in HTTP Request parsing","id":"CVE-2023-50269","kev_date_added":null,"published":"2023-12-14"},{"cvss_score":8.6,"headline":"Denial of Service in HTTP Message Processing in Squid","id":"CVE-2023-49285","kev_date_added":null,"published":"2023-12-04"},{"cvss_score":8.6,"headline":"Denial of Service in Helper Process management","id":"CVE-2023-49286","kev_date_added":null,"published":"2023-12-04"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Red Hat","prefix":"RHSA"},{"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 cause a denial of service in Squid proxy servers via crafted HTTP requests leading to memory exhaustion.","url":"https://insights.sbomify.com/CVE-2012-5643/"}
