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-2018-1000654 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2018-1000654/ (Markdown: https://insights.sbomify.com/CVE-2018-1000654/index.md)","id":"CVE-2018-1000654","markdown":"https://insights.sbomify.com/CVE-2018-1000654/index.md","name":"CVE-2018-1000654","record":{"aliases":["ALPINE-CVE-2018-1000654","DEBIAN-CVE-2018-1000654","GHSA-g69v-w5wh-rhwv","MGASA-2019-0359","SUSE-SU-2019:1372-1","SUSE-SU-2019:1372-2","UBUNTU-CVE-2018-1000654","USN-5352-1","openSUSE-SU-2019:1498-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Libtasn1 library","requires_auth":"none","summary":"Attackers can cause a denial of service by providing a crafted file that triggers excessive CPU usage in the ASN.1 parser.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"libtasn1","vendor":"gnu"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12 contains a DoS, specifically CPU usage will reach 100% when running asn1Paser against the POC due to an issue in _asn1_expand_object_id(p_tree), after a long time, the program will be killed.
