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-2020-14344 and fix it if it is affected.\n\nWhat it is: CVE-2020-14344 is a medium-severity vulnerability in Canonical Ubuntu Linux, published on 5 Aug 2020. 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-2020-14344 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-2020-14344/ (Markdown: https://insights.sbomify.com/CVE-2020-14344/index.md)","id":"CVE-2020-14344","markdown":"https://insights.sbomify.com/CVE-2020-14344/index.md","name":"CVE-2020-14344","record":{"aliases":["ALPINE-CVE-2020-14344","DEBIAN-CVE-2020-14344","DLA-2312-1","GHSA-g6cq-58wq-v493","JLSEC-2026-469","MGASA-2020-0334","SUSE-SU-2020:14445-1","SUSE-SU-2020:14447-1","SUSE-SU-2020:2116-1","SUSE-SU-2020:2117-1","SUSE-SU-2020:2196-1","SUSE-SU-2020:2197-1","UBUNTU-CVE-2020-14344","openSUSE-SU-2020:1162-1","openSUSE-SU-2020:1164-1","openSUSE-SU-2020:1182-1","openSUSE-SU-2020:1198-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"X11 client library","requires_auth":"high_privilege","summary":"An integer overflow in libX11 can lead to heap corruption and privilege escalation when setuid programs invoke XIM client functions.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"},{"product":"libx11","vendor":"x.org"}],"cvss":{"score":6.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow leading to a heap-buffer overflow was found in The X Input Method (XIM) client was implemented in libX11 before version 1.6.10.
