Huawei EulerOS: Security Advisory for kvm (EulerOS-SA-2018-1271)

The remote host is missing an update for the Huawei EulerOS 'kvm' package(s) announced via the EulerOS-SA-2018-1271 advisory.

An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update 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 read privileged memory by conducting targeted cache side-channel attacks.(CVE-2018-3639)

'kvm' package(s) on Huawei EulerOS Virtualization 2.5.0.

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

Please install the updated package(s).
