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-2021-35517 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.commons:commons-compress (Maven): affected all versions; fixed in 1.21\n- org.apache.commons:commons-compress (Maven): affected all versions; fixed in 1.21\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-2021-35517/ (Markdown: https://insights.sbomify.com/CVE-2021-35517/index.md)","id":"CVE-2021-35517","markdown":"https://insights.sbomify.com/CVE-2021-35517/index.md","name":"CVE-2021-35517","record":{"aliases":["AZL-44490","DEBIAN-CVE-2021-35517","GHSA-xqfj-vm6h-2x34","MINI-gcmg-xm3j-cfv6","ROOT-APP-MAVEN-CVE-2021-35517","UBUNTU-CVE-2021-35517"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java compression library","requires_auth":"none","summary":"Attackers can cause denial of service by triggering excessive memory allocation via crafted TAR archives in Apache Commons Compress.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"commons_compress","vendor":"apache"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"oncommand_insight","vendor":"netapp"},{"product":"banking_apis","vendor":"oracle"},{"product":"banking_digital_experience","vendor":"oracle"},{"product":"banking_enterprise_default_management","vendor":"oracle"},{"product":"banking_party_management","vendor":"oracle"},{"product":"banking_payments","vendor":"oracle"},{"product":"banking_trade_finance","vendor":"oracle"},{"product":"banking_treasury_management","vendor":"oracle"},{"product":"business_process_management_suite","vendor":"oracle"},{"product":"commerce_guided_search","vendor":"oracle"},{"product":"communications_billing_and_revenue_management","vendor":"oracle"},{"product":"communications_cloud_native_core_service_communication_proxy","vendor":"oracle"},{"product":"communications_cloud_native_core_unified_data_repository","vendor":"oracle"},{"product":"communications_diameter_intelligence_hub","vendor":"oracle"},{"product":"communications_messaging_server","vendor":"oracle"},{"product":"communications_session_route_manager","vendor":"oracle"},{"product":"financial_services_crime_and_compliance_management_studio","vendor":"oracle"},{"product":"financial_services_enterprise_case_management","vendor":"oracle"},{"product":"flexcube_universal_banking","vendor":"oracle"},{"product":"healthcare_data_repository","vendor":"oracle"},{"product":"insurance_policy_administration","vendor":"oracle"},{"product":"peoplesoft_enterprise_peopletools","vendor":"oracle"},{"product":"primavera_unifier","vendor":"oracle"},{"product":"utilities_testing_accelerator","vendor":"oracle"},{"product":"webcenter_portal","vendor":"oracle"}],"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"},{"id":"CWE-130","name":"Improper Handling of Length Parameter Inconsistency"}],"description":"When reading a specially crafted TAR archive, Compress can be made to allocate large amounts of memory that finally leads to an out of memory error even for very small inputs.
