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-2019-4523 and fix it if it is affected.\n\nWhat it is: CVE-2019-4523 is a high-severity memory corruption vulnerability in IBM DB2 High Performance Unload load for LUW, published on 22 Oct 2019. 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-2019-4523 in the wild and no public exploit code.\n\nAffected product: IBM DB2 High Performance Unload load for LUW. 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-2019-4523/ (Markdown: https://insights.sbomify.com/CVE-2019-4523/index.md)","id":"CVE-2019-4523","markdown":"https://insights.sbomify.com/CVE-2019-4523/index.md","name":"CVE-2019-4523","record":{"aliases":["GHSA-8xjf-2mv7-wrhw"],"analysis":{"component_type":"database","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IBM DB2 Unload","requires_auth":"none","summary":"A local attacker can exploit a buffer overflow in IBM DB2 High Performance Unload to execute arbitrary code with root privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"db2_high_performance_unload_load","vendor":"ibm"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.0/PR:N/AV:L/UI:N/C:H/I:H/A:H/S:U/AC:L/RL:O/E:U/RC:C","version":"3.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"IBM DB2 High Performance Unload load for LUW 6.1 and 6.5 is vulnerable to a buffer overflow, caused by improper bounds checking which could allow a local attacker to execute arbitrary code on the system with root privileges.
