Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2018-1323)

The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2018-1323 advisory.

Modern operating systems implement virtualization of physical memory to efficiently use available system resources and provide inter-domain protection through access control and isolation. The L1TF issue was found in the way the x86 microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimisation) in combination with handling of page-faults caused by terminated virtual to physical address resolving process. As a result, an unprivileged attacker could use this flaw to read privileged memory of the kernel or other processes and/or cross guest/host boundaries to read host memory by conducting targeted cache side-channel attacks. (CVE-2018-3620, CVE-2018-3646)

'kernel' package(s) on Huawei EulerOS Virtualization 2.5.1.

Checks if a vulnerable package version is present on the target host.

Please install the updated package(s).
