It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2018-1000156 and fix it if it is affected.\n\nWhat it is: CVE-2018-1000156 is a high-severity code injection vulnerability in Canonical Ubuntu Linux, published on 6 Apr 2018. 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-2018-1000156 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-2018-1000156/ (Markdown: https://insights.sbomify.com/CVE-2018-1000156/index.md)","id":"CVE-2018-1000156","markdown":"https://insights.sbomify.com/CVE-2018-1000156/index.md","name":"CVE-2018-1000156","record":{"aliases":["ALPINE-CVE-2018-1000156","AZL-35101","AZL-6785","CLEANSTART-2026-ZQ70340","DEBIAN-CVE-2018-1000156","DLA-1348-1","GHSA-r9rq-mhxg-686q","JLSEC-2026-12","RHSA-2018:1199","RHSA-2018:1200","RHSA-2018:2091","RHSA-2018:2092","RHSA-2018:2093","RHSA-2018:2094","RHSA-2018:2095","RHSA-2018:2096","RHSA-2018:2097","UBUNTU-CVE-2018-1000156","openSUSE-SU-2024:11372-1"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Patch utility","requires_auth":"none","summary":"Attackers can execute arbitrary code by crafting a malicious patch file processed by the GNU Patch utility, requiring users to update the tool.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"patch","vendor":"gnu"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_server_tus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution.
