Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2015-5239 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2015-5239/ (Markdown: https://insights.sbomify.com/CVE-2015-5239/index.md)","id":"CVE-2015-5239","markdown":"https://insights.sbomify.com/CVE-2015-5239/index.md","name":"CVE-2015-5239","record":{"aliases":["DEBIAN-CVE-2015-5239","GHSA-9mm7-7f84-98c9","UBUNTU-CVE-2015-5239"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"QEMU virtualization","requires_auth":"low_privilege","summary":"An integer overflow in QEMU's VNC driver allows attackers to cause a denial of service via a crafted message, impacting virtualization infrastructure.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"eos","vendor":"arista"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"fedora","vendor":"fedoraproject"},{"product":"qemu","vendor":"qemu"},{"product":"linux_enterprise_debuginfo","vendor":"suse"},{"product":"linux_enterprise_desktop","vendor":"suse"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"linux_enterprise_software_development_kit","vendor":"suse"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"}],"description":"Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in QEMU","id":"CVE-2015-5239","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"canonical:ubuntu_linux","products":["canonical:ubuntu_linux","fedoraproject:fedora","qemu:qemu","suse:linux_enterprise_debuginfo","suse:linux_enterprise_desktop","suse:linux_enterprise_server","suse:linux_enterprise_software_development_kit"],"type":"integer_overflow","year":"2015"},"n_packages":0,"n_references":10,"next":{"headline":"OpenStack Neutron Race condition vulnerability","id":"CVE-2015-5240"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2015-5237"},"products":["QEMU"],"published":"2020-01-23","related":[{"cvss_score":6.9,"headline":"Arista Extensible Operating System Incomplete Comparison with Missing Factors","id":"CVE-2026-7473","kev_date_added":"2026-06-09","published":"2026-06-05"},{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2015-8236","kev_date_added":null,"published":"2015-11-19"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2020-10188","kev_date_added":null,"published":"2020-03-06"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-18017","kev_date_added":null,"published":"2018-01-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-14491","kev_date_added":null,"published":"2017-10-02"},{"cvss_score":9.3,"headline":"Privilege escalation in Arista EOS","id":"CVE-2023-24509","kev_date_added":null,"published":"2023-04-13"},{"cvss_score":9.3,"headline":"Information disclosure in n/a","id":"CVE-2015-5165","kev_date_added":null,"published":"2015-08-12"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["QEMU"]},"summary":"An integer overflow in QEMU's VNC driver allows attackers to cause a denial of service via a crafted message, impacting virtualization infrastructure.","url":"https://insights.sbomify.com/CVE-2015-5239/"}
