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-2023-34325 in the wild and no public exploit code.\n\nAffected product: Xen Xen. 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-2023-34325/ (Markdown: https://insights.sbomify.com/CVE-2023-34325/index.md)","id":"CVE-2023-34325","markdown":"https://insights.sbomify.com/CVE-2023-34325/index.md","name":"CVE-2023-34325","record":{"aliases":["ALPINE-CVE-2023-34325","DEBIAN-CVE-2023-34325","GHSA-gwmw-qvr5-88j2","UBUNTU-CVE-2023-34325"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"A stack buffer overflow in Xen's libfsimage allows guest-controlled input to trigger memory corruption, potentially leading to code execution with root privileges.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[{"product":"xen","vendor":"xen"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"[This CNA information record relates to multiple CVEs; the\ntext explains which aspects/vulnerabilities correspond to which CVE.]\n\nlibfsimage contains parsing code for several filesystems, most of them based on\ngrub-legacy code.  libfsimage is used by pygrub to inspect guest disks.\n\nPygrub runs as the same user as the toolstack (root in a priviledged domain).\n\nAt least one issue has been reported to the Xen Security Team that allows an\nattacker to trigger a stack buffer overflow in libfsimage.
