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-2020-27792 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-2020-27792/ (Markdown: https://insights.sbomify.com/CVE-2020-27792/index.md)","id":"CVE-2020-27792","markdown":"https://insights.sbomify.com/CVE-2020-27792/index.md","name":"CVE-2020-27792","record":{"aliases":["DEBIAN-CVE-2020-27792","DLA-3096-1","GHSA-7h9w-vh8m-rj5g","UBUNTU-CVE-2020-27792","USN-5618-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ghostscript library","requires_auth":"none","summary":"An attacker can cause memory corruption or denial of service by tricking a user into opening a crafted PDF file processed by Ghostscript.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ghostscript","vendor":"artifex"},{"product":"debian_linux","vendor":"debian"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A heap-based buffer overwrite vulnerability was found in GhostScript's lp8000_print_page() function in the gdevlp8k.c file.
