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-2021-39293 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.16.8, 1.17.1\n- stdlib (Go): affected all versions; fixed in 1.16.8, 1.17.1\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-2021-39293/ (Markdown: https://insights.sbomify.com/CVE-2021-39293/index.md)","id":"CVE-2021-39293","markdown":"https://insights.sbomify.com/CVE-2021-39293/index.md","name":"CVE-2021-39293","record":{"aliases":["BIT-golang-2021-39293","DEBIAN-CVE-2021-39293","GHSA-j532-8pqq-78jr","GO-2022-0273","OESA-2022-1518","SUSE-RU-2021:3315-1","SUSE-SU-2021:3292-1","UBUNTU-CVE-2021-39293","openSUSE-SU-2021:1342-1","openSUSE-SU-2021:3292-1","openSUSE-SU-2024:10810-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"A crafted zip archive header causes a panic in the Go standard library, leading to denial of service for applications using the archive/zip package.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"go","vendor":"golang"},{"product":"cloud_insights_telegraf","vendor":"netapp"}],"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-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"In archive/zip in Go before 1.16.8 and 1.17.x before 1.17.1, a crafted archive header (falsely designating that many files are present) can cause a NewReader or OpenReader panic.
