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-2019-18397 and fix it if it is affected.\n\nWhat it is: CVE-2019-18397 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 13 Nov 2019. 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-2019-18397 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-2019-18397/ (Markdown: https://insights.sbomify.com/CVE-2019-18397/index.md)","id":"CVE-2019-18397","markdown":"https://insights.sbomify.com/CVE-2019-18397/index.md","name":"CVE-2019-18397","record":{"aliases":["ALPINE-CVE-2019-18397","DEBIAN-CVE-2019-18397","DSA-4561-1","GHSA-fcm8-q275-jqv2","JLSEC-2025-169","MGASA-2019-0325","RHSA-2019:4326","RHSA-2019:4361","RHSA-2020:0291","SUSE-SU-2021:1655-1","openSUSE-SU-2021:0763-1","openSUSE-SU-2021:1655-1","openSUSE-SU-2024:10772-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU FriBidi library","requires_auth":"none","summary":"A buffer overflow in GNU FriBidi allows attackers to execute arbitrary code or cause denial of service via crafted text content rendered by applications using the library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fribidi","vendor":"gnu"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"A buffer overflow in the fribidi_get_par_embedding_levels_ex() function in lib/fribidi-bidi.c of GNU FriBidi through 1.0.7 allows an attacker to cause a denial of service or possibly execute arbitrary code by delivering crafted text content to a user, when this content is then rendered by an application that uses FriBidi for text layout calculations.
