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-2023-50229 in the wild and no public exploit code.\n\nAffected product: BlueZ. 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-2023-50229/ (Markdown: https://insights.sbomify.com/CVE-2023-50229/index.md)","id":"CVE-2023-50229","markdown":"https://insights.sbomify.com/CVE-2023-50229/index.md","name":"CVE-2023-50229","record":{"aliases":["AZL-40217","AZL-40267","DEBIAN-CVE-2023-50229","GHSA-5p3x-h55j-m7f2","OESA-2024-1029","ROOT-OS-ALPINE-318-CVE-2023-50229","UBUNTU-CVE-2023-50229"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"BlueZ Bluetooth stack","requires_auth":"none","summary":"Network-adjacent attackers can execute arbitrary code with root privileges via a heap buffer overflow in BlueZ's Phone Book Access Profile.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"bluez","vendor":"bluez"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"BlueZ Phone Book Access Profile Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of BlueZ.

The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer.
