It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-27919 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected from 1.16.0; fixed in 1.16.1\n- stdlib (Go): affected from 1.16.0-0; fixed in 1.16.1\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-2021-27919/ (Markdown: https://insights.sbomify.com/CVE-2021-27919/index.md)","id":"CVE-2021-27919","markdown":"https://insights.sbomify.com/CVE-2021-27919/index.md","name":"CVE-2021-27919","record":{"aliases":["BIT-golang-2021-27919","GHSA-v7gg-6p99-5jxq","GO-2021-0067","UBUNTU-CVE-2021-27919"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"Attackers can cause a denial of service via panic in Go's zip reader when processing archives with path traversal sequences in filenames.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"go","vendor":"golang"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"archive/zip in Go 1.16.x before 1.16.1 allows attackers to cause a denial of service (panic) upon attempted use of the Reader.Open API for a ZIP archive in which ../ occurs at the beginning of any filename.","ecosystems":["Bitnami","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":"Path traversal in n/a","id":"CVE-2021-27919","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"fedoraproject:fedora","products":["fedoraproject:fedora","golang:go"],"type":"path_traversal","year":"2021"},"n_packages":2,"n_references":4,"next":{"headline":"Pillow Denial of Service by Uncontrolled Resource Consumption","id":"CVE-2021-27921"},"packages":[{"ecosystem":"Bitnami","fixed":["1.16.1"],"introduced":["1.16.0"],"last_affected":[],"package":"golang","purl":"pkg:bitnami/golang","source":"BIT-golang-2021-27919"},{"ecosystem":"Go","fixed":["1.16.1"],"introduced":["1.16.0-0"],"last_affected":[],"package":"stdlib","purl":"pkg:golang/stdlib","source":"GO-2021-0067"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-27918"},"products":["n/a"],"published":"2021-03-11","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":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-03","vendors":["n/a"]},"summary":"Attackers can cause a denial of service via panic in Go's zip reader when processing archives with path traversal sequences in filenames.","url":"https://insights.sbomify.com/CVE-2021-27919/"}
