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-2021-35942 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2021-35942/ (Markdown: https://insights.sbomify.com/CVE-2021-35942/index.md)","id":"CVE-2021-35942","markdown":"https://insights.sbomify.com/CVE-2021-35942/index.md","name":"CVE-2021-35942","record":{"aliases":["CLSA-2026-1777456776","DEBIAN-CVE-2021-35942","GHSA-53wq-r63f-m33q","MGASA-2021-0362","OESA-2021-1296","UBUNTU-CVE-2021-35942"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"GNU C Library","requires_auth":"none","summary":"An integer overflow in glibc's wordexp function allows attackers to cause crashes or read arbitrary memory via crafted patterns.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"glibc","vendor":"gnu"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"e-series_santricity_os_controller","vendor":"netapp"},{"product":"hci_management_node","vendor":"netapp"},{"product":"ontap_select_deploy_administration_utility","vendor":"netapp"},{"product":"solidfire","vendor":"netapp"}],"cvss":{"score":9.1,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"},{"id":"CWE-704","name":"Incorrect Type Conversion or Cast"}],"description":"The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information.
