It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-6377 and fix it if it is affected.\n\nWhat it is: CVE-2023-6377 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 13 Dec 2023. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-6377 in the wild and no public exploit code.\n\nAffected product: Debian Debian 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-2023-6377/ (Markdown: https://insights.sbomify.com/CVE-2023-6377/index.md)","id":"CVE-2023-6377","markdown":"https://insights.sbomify.com/CVE-2023-6377/index.md","name":"CVE-2023-6377","record":{"aliases":["AZL-32179","AZL-44700","BELL-CVE-2023-6377","CLSA-2025-1763558418","DEBIAN-CVE-2023-6377","DLA-3686-2","DSA-5576-2","GHSA-xp6x-8hgv-x5w5","RHSA-2025:13998","SUSE-SU-2023:4925-1","SUSE-SU-2023:4926-1","SUSE-SU-2023:4933-1","SUSE-SU-2023:4934-1","SUSE-SU-2023:4935-1","SUSE-SU-2023:4949-1","UBUNTU-CVE-2023-6377"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xorg X11 server","requires_auth":"low_privilege","summary":"Out-of-bounds memory access in Xorg X11 server allows local privilege escalation or remote code execution via X11 forwarding.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"enterprise_linux_eus","vendor":"redhat"},{"product":"tigervnc","vendor":"tigervnc"},{"product":"x_server","vendor":"x.org"},{"product":"xwayland","vendor":"x.org"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"A flaw was found in xorg-server.
