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-2018-1056 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2018-1056/ (Markdown: https://insights.sbomify.com/CVE-2018-1056/index.md)","id":"CVE-2018-1056","markdown":"https://insights.sbomify.com/CVE-2018-1056/index.md","name":"CVE-2018-1056","record":{"aliases":["DEBIAN-CVE-2018-1056","DLA-1281-1","GHSA-557x-wcm4-fhw8","MGASA-2018-0141","UBUNTU-CVE-2018-1056","USN-3570-1"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ZIP compression utility","requires_auth":"none","summary":"An attacker can crash the advzip utility by tricking it into processing crafted ZIP files, causing a denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"advancecomp","vendor":"advancemame"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"An out-of-bounds heap buffer read flaw was found in the way advancecomp before 2.1-2018/02 handled processing of ZIP files.
