An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-2794 exists.\n\nAffected product: Fedoraproject Fedora. 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-2023-2794/ (Markdown: https://insights.sbomify.com/CVE-2023-2794/index.md)","id":"CVE-2023-2794","markdown":"https://insights.sbomify.com/CVE-2023-2794/index.md","name":"CVE-2023-2794","record":{"aliases":["DEBIAN-CVE-2023-2794","GHSA-qcrm-33g9-cjcc","UBUNTU-CVE-2023-2794"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Linux telephony stack","requires_auth":"none","summary":"A stack-based buffer overflow in the ofono SMS decoder allows remote code execution via malicious SMS or base station interactions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"ofono","vendor":"ofono_project"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/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 flaw was found in ofono, an Open Source Telephony on Linux.
