Document Subtype: Security Bulletin Document ID: hpesbhf03850en_us Last Updated: 2018-06-13 Release Date: 2018-06-12 Document Version: 1 Potential Security Impact: Local: Disclosure of Information Source: Hewlett Packard Enterprise, HPE Product Security Response Team VULNERABILITY SUMMARY Security vulnerabilities involving speculative execution in microprocessors from Intel and AMD used in HPE ProLiant and HPE Synergy servers could allow the local disclosure of information. Resolution of these vulnerabilities requires operating system updates provided by the operating system vendor, software updates, and system ROM updates from HPE. There are two vulnerabilities: Variant 4, Speculative Store Bypass, (CVE-2018-3639) affects Intel and AMD processor-based systems and requires updated microcode (delivered as part of the BIOS), operating system updates, and software updates. Variant 3A, Rogue Register Load, (CVE-2018-3640) affects Intel processors only and requires a System ROM update. References: PSRT110755 CVE-2018-3639 - Variant 4, Speculative Store Bypass CVE-2018-3640 - Variant 3A, Rogue Register Load SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
