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-2023-4042 in the wild and no public exploit code.\n\nAffected product: Artifex Ghostscript. 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-2023-4042/ (Markdown: https://insights.sbomify.com/CVE-2023-4042/index.md)","id":"CVE-2023-4042","markdown":"https://insights.sbomify.com/CVE-2023-4042/index.md","name":"CVE-2023-4042","record":{"aliases":["GHSA-jgj3-64jr-4g3x"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Red Hat Enterprise Linux","requires_auth":"none","summary":"Ghostscript in Red Hat Enterprise Linux 8 contains an incomplete fix for a memory corruption flaw, potentially allowing code execution or denial of service.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ghostscript","vendor":"artifex"},{"product":"codeready_linux_builder","vendor":"redhat"},{"product":"codeready_linux_builder_for_arm64","vendor":"redhat"},{"product":"codeready_linux_builder_for_ibm_z_systems","vendor":"redhat"},{"product":"codeready_linux_builder_for_power_little_endian","vendor":"redhat"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"enterprise_linux_for_arm_64","vendor":"redhat"},{"product":"enterprise_linux_for_ibm_z_systems","vendor":"redhat"},{"product":"enterprise_linux_for_power_little_endian","vendor":"redhat"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in ghostscript.
