An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2015-8555 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-2015-8555/ (Markdown: https://insights.sbomify.com/CVE-2015-8555/index.md)","id":"CVE-2015-8555","markdown":"https://insights.sbomify.com/CVE-2015-8555/index.md","name":"CVE-2015-8555","record":{"aliases":["DEBIAN-CVE-2015-8555","GHSA-ffhp-28g8-p5m9","UBUNTU-CVE-2015-8555"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"none","summary":"Local guest domains can read sensitive information from other domains due to uninitialized FPU and XMM registers in Xen hypervisor.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"xenserver","vendor":"citrix"},{"product":"xen","vendor":"xen"}],"cvss":{"score":8.6,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"Xen 4.6.x, 4.5.x, 4.4.x, 4.3.x, and earlier do not initialize x86 FPU stack and XMM registers when XSAVE/XRSTOR are not used to manage guest extended register state, which allows local guest domains to obtain sensitive information from other domains via unspecified vectors.","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":"Information disclosure in n/a","id":"CVE-2015-8555","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"citrix:xenserver","products":["citrix:xenserver","xen:xen"],"type":"information_disclosure","year":"2015"},"n_packages":0,"n_references":7,"next":{"headline":"Race condition in n/a","id":"CVE-2015-8556"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2015-8554"},"products":["n/a"],"published":"2016-04-13","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2014-4947","kev_date_added":null,"published":"2014-07-22"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2018-14007","kev_date_added":null,"published":"2018-08-15"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2015-7705","kev_date_added":null,"published":"2017-08-07"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2016-5302","kev_date_added":null,"published":"2016-06-13"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12134","kev_date_added":null,"published":"2017-08-24"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-12135","kev_date_added":null,"published":"2017-08-24"},{"cvss_score":8.8,"headline":"Privilege escalation in n/a","id":"CVE-2017-12137","kev_date_added":null,"published":"2017-08-24"}],"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":["n/a"]},"summary":"Local guest domains can read sensitive information from other domains due to uninitialized FPU and XMM registers in Xen hypervisor.","url":"https://insights.sbomify.com/CVE-2015-8555/"}
