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-2018-1923 in the wild and no public exploit code.\n\nAffected product: Ibm Db2. 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-2018-1923/ (Markdown: https://insights.sbomify.com/CVE-2018-1923/index.md)","id":"CVE-2018-1923","markdown":"https://insights.sbomify.com/CVE-2018-1923/index.md","name":"CVE-2018-1923","record":{"aliases":["GHSA-mcxh-m5cm-35cq"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM DB2 database","requires_auth":"none","summary":"A buffer overflow in IBM DB2 allows attackers to execute arbitrary code on the database server.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"db2","vendor":"ibm"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.0/A:H/AC:L/AV:L/C:H/I:H/PR:N/S:U/UI:N/E:U/RC:C/RL:O","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) 9.7, 10.1, 10.5, and 11.1 is affected by buffer overflow vulnerability that can potentially result in arbitrary code execution.
