MiracleLinux 7 : linux-firmware-20170606-57.gitc990aae.el7 (AXSA:2018-2499:01)
medium Nessus Plugin ID 289392
Synopsis
The remote MiracleLinux host is missing a security update.Description
The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2018-2499:01 advisory.* 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.
Asianux would like to thank Google Project Zero for reporting this issue.
CVE-2017-5715 Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
