EulerOS 2.0 SP8 : libvirt (EulerOS-SA-2019-2289)

medium Nessus Plugin ID 131355

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the libvirt packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - Microarchitectural Store Buffer Data Sampling (MSBDS):
 Store buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here:

 - Microarchitectural Load Port Data Sampling (MLPDS):
 Load ports on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here:
 https://www.intel.com/content/dam/www/public/us/en/docu ments/corporate-information/SA00233-microcode-update-gu idance_05132019.pdf(CVE-2018-12127)

 - Microarchitectural Fill Buffer Data Sampling (MFBDS):
 Fill buffers on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here:
 https://www.intel.com/content/dam/www/public/us/en/docu ments/corporate-information/SA00233-microcode-update-gu idance_05132019.pdf(CVE-2018-12130)

 - Microarchitectural Data Sampling Uncacheable Memory (MDSUM): Uncacheable memory on some microprocessors utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. A list of impacted products can be found here:
 https://www.intel.com/content/dam/www/public/us/en/docu ments/corporate-information/SA00233-microcode-update-gu idance_05132019.pdf(CVE-2019-11091)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
