Synopsis: Important: linux-firmware security update Advisory ID: SLSA-2018:0014-1 Issue Date: 2018-01-04 CVE Numbers: CVE-2017-5715 -- 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. 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) Note: This is the microcode counterpart of the CVE-2017-5715 kernel mitigation. -- SL7 noarch iwl100-firmware-39.31.5.1-57.el7_4.noarch.rpm iwl1000-firmware-39.31.5.1-57.el7_4.noarch.rpm iwl105-firmware-18.168.6.1-57.el7_4.noarch.rpm iwl135-firmware-18.168.6.1-57.el7_4.noarch.rpm iwl2000-firmware-18.168.6.1-57.el7_4.noarch.rpm iwl2030-firmware-18.168.6.1-57.el7_4.noarch.rpm iwl3160-firmware-22.0.7.0-57.el7_4.noarch.rpm iwl3945-firmware-15.32.2.9-57.el7_4.noarch.rpm iwl4965-firmware-228.61.2.24-57.el7_4.noarch.rpm iwl5000-firmware-8.83.5.1_1-57.el7_4.noarch.rpm iwl5150-firmware-8.24.2.2-57.el7_4.noarch.rpm iwl6000-firmware-9.221.4.1-57.el7_4.noarch.rpm iwl6000g2a-firmware-17.168.5.3-57.el7_4.noarch.rpm iwl6000g2b-firmware-17.168.5.2-57.el7_4.noarch.rpm iwl6050-firmware-41.28.5.1-57.el7_4.noarch.rpm iwl7260-firmware-22.0.7.0-57.el7_4.noarch.rpm iwl7265-firmware-22.0.7.0-57.el7_4.noarch.rpm linux-firmware-20170606-57.gitc990aae.el7_4.noarch.rpm - Scientific Linux Development Team
