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-2018-17847 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang.org/x/net (Go): affected all versions; fixed in 0.0.0-20190125002852-4b62a64f59f7\n- golang.org/x/net (Go): affected all versions; fixed in 0.0.0-20190125002852-4b62a64f59f7\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-2018-17847/ (Markdown: https://insights.sbomify.com/CVE-2018-17847/index.md)","id":"CVE-2018-17847","markdown":"https://insights.sbomify.com/CVE-2018-17847/index.md","name":"CVE-2018-17847","record":{"aliases":["GHSA-4r78-hx75-jjj2"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go HTML parser","requires_auth":"none","summary":"A crafted HTML input causes a runtime panic in the Go html package, leading to a denial of service for applications using the parser.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"net","vendor":"golang"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"The html package (aka x/net/html) through 2018-09-25 in Go mishandles \u003csvg\u003e\u003ctemplate\u003e\u003cdesc\u003e\u003ct\u003e\u003csvg\u003e\u003c/template\u003e, leading to a \"panic: runtime error\" (index out of range) in (*nodeStack).pop in node.go, called from (*parser).clearActiveFormattingElements, during an html.Parse call.","ecosystems":["Go"],"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":"golang.org/x/net/html has Improper Restriction of Operations within the Bounds of a Memory Buffer","id":"CVE-2018-17847","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"denial_of_service","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"golang.org/x/net/html Improper Validation of Array Index vulnerability","id":"CVE-2018-17848"},"packages":[{"ecosystem":"Go","fixed":["0.0.0-20190125002852-4b62a64f59f7"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/net","purl":null,"source":"GHSA-4r78-hx75-jjj2"},{"ecosystem":"Go","fixed":["0.0.0-20190125002852-4b62a64f59f7"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/net","purl":"pkg:golang/golang.org/x/net","source":"GHSA-4r78-hx75-jjj2"}],"prev":{"headline":"x/net/html Vulnerable to DoS During HTML Parsing","id":"CVE-2018-17846"},"products":["n/a"],"published":"2018-10-01","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"A crafted HTML input causes a runtime panic in the Go html package, leading to a denial of service for applications using the parser.","url":"https://insights.sbomify.com/CVE-2018-17847/"}
