TITLE

CPU hardware utilizing speculative execution may be vulnerable to cache side-channel attacks

DESCRIPTION

Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Two vulnerabilities are identified, known as "Variant 3a" and "Variant 4". Has speculative execution function and out-of-order execution function CPU Several researchers have reported methods of performing side-channel attacks against Has speculative execution function and out-of-order execution function CPU side-channel attack method against (Spectre and Meltdown) has been reported. For more information, Google Project Zero blog post in ("Reading privileged memory with a side-channel") or Graz University of Technology (TU Graz) information from researchers in ("Meltdown and Spectre") Please refer to. "Reading privileged memory with a side-channel"https://googleprojectzero.blogspot.jp/2018/01/reading-privileged-memory-with-side.html"Meltdown and Spectre"https://meltdownattack.com/Sensitive information can be obtained from processes running with user privileges. Spectre As for the attack, crafted Javascript by the code Javascript cannot be obtained from web It has been reported that data can be obtained during the browser process. CPUhardware is a set of firmware that runs in the CPU (Central Processing Unit) for managing and controlling the CPU. The Meltdown vulnerability exists in the CPU processor core, which \"melts\" the security boundary implemented by hardware, allowing low-privileged user-level applications to \"cross-border\" access to system-level memory, causing data leakage. The following products and versions are affected: ARM Cortex-R7; Cortex-R8; Cortex-A8; Cortex-A9; Cortex-A12; Xeon CPU E5-1650 v3, v2, v4; Xeon E3-1265l v2, v3, v4 ; Xeon E3-1245 v2, v3, v5, v6 versions; Xeon X7542, etc. ========================================================================== Ubuntu Security Notice USN-3540-2 January 23, 2018 linux-lts-xenial, linux-aws vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS Summary: Several security issues were addressed in the Linux kernel.

Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact. In this update mitigations for x86-64 architecture are provided. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall boundary and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5753, Important) Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks. (CVE-2017-5715, Important) Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. (CVE-2017-5754, Important) Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. Red Hat would like to thank Google Project Zero for reporting these issues. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5.

Intel has now identified the root cause of these issues and determined that these microcodes may introduce reboots and other unpredictable system behavior. Due to the severity of the potential issues that may occur when using these microcodes, Intel is now recommending that customers discontinue their use. Additional information is available from Intels Security Exploit Newsroom here: <https://newsroom.intel.com/press-kits/security-exploits-intel-products/> . HPE is in alignment with Intel in our recommendation that customers discontinue use of System ROMs including impacted microcodes and revert to earlier System ROM versions. All System ROMs including impacted microcodes have been removed from the HPE Support Site. This impacts HPE ProLiant and Synergy Gen10, Gen9, and Gen8 v2 servers as well as HPE Superdome servers for which updated System ROMs had previously been made available. Intel is working on updated microcodes to address these issues, and HPE will validate updated System ROMs including these microcodes and make them available to our customers in the coming weeks. Mitigations for Variant 1 (Spectre) and Variant 3 (Meltdown) vulnerabilities require only OS updates and are not impacted. * HPE has provided a customer bulletin <https://support.hpe.com/hpsc/doc/public/display?docId=emr_na-a00039267en_us> with specific instructions to obtain the udpated sytem ROM - Note: + CVE-2017-5715 (Variant 2) requires that the System ROM be updated and a vendor supplied operating system update be applied as well. + For CVE-2017-5753, CVE-2017-5754 (Variants 1 and 3) require only updates of a vendor supplied operating system. + HPE will continue to add additional products to the list.
