The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2392 advisory.

    The kernel packages contain the Linux kernel, the core of any Linux operating system.

    Security Fix(es):

    * 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: kvm: vmx: host GDT limit corruption (CVE-2018-10901)

    For more details about the security issue(s), including the impact, a CVSS score, and other related     information, refer to the CVE page(s) listed in the References section.

    Red Hat would like to thank Intel OSSIRT (Intel.com) for reporting CVE-2018-3620 and CVE-2018-3646 and     Vegard Nossum (Oracle Corporation) for reporting CVE-2018-10901.
