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-2016-9603 in the wild and no public exploit code.\n\nAffected product: Citrix Xenserver. 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-2016-9603/ (Markdown: https://insights.sbomify.com/CVE-2016-9603/index.md)","id":"CVE-2016-9603","markdown":"https://insights.sbomify.com/CVE-2016-9603/index.md","name":"CVE-2016-9603","record":{"aliases":["ALPINE-CVE-2016-9603","DEBIAN-CVE-2016-9603","GHSA-49mx-v59p-m55m","RHSA-2017:0985","RHSA-2017:0987","UBUNTU-CVE-2016-9603"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"QEMU emulator","requires_auth":"low_privilege","summary":"A heap buffer overflow in QEMU's Cirrus VGA emulator allows guest users to crash the host or execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"xenserver","vendor":"citrix"},{"product":"debian_linux","vendor":"debian"},{"product":"qemu","vendor":"qemu"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_server_aus","vendor":"redhat"},{"product":"enterprise_linux_server_eus","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"openstack","vendor":"redhat"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:A/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap buffer overflow flaw was found in QEMU's Cirrus CLGD 54xx VGA emulator's VNC display driver support before 2.9; the issue could occur when a VNC client attempted to update its display after a VGA operation is performed by a guest.
