Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1711 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2020-1711/ (Markdown: https://insights.sbomify.com/CVE-2020-1711/index.md)","id":"CVE-2020-1711","markdown":"https://insights.sbomify.com/CVE-2020-1711/index.md","name":"CVE-2020-1711","record":{"aliases":["DEBIAN-CVE-2020-1711","GHSA-8gvc-95pj-x5r8","RHSA-2020:0669","RHSA-2020:0731","RHSA-2020:0773","RHSA-2020:1505","RHSA-2020:2472","UBUNTU-CVE-2020-1711"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"QEMU virtualization","requires_auth":"low_privilege","summary":"A remote attacker can crash QEMU or execute arbitrary code via a malicious iSCSI server response due to an out-of-bounds heap buffer access.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"leap","vendor":"opensuse"},{"product":"qemu","vendor":"qemu"},{"product":"enterprise_linux","vendor":"redhat"},{"product":"openstack","vendor":"redhat"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine.
