According to the versions of the anaconda / anaconda-core / anaconda-dracut / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the way the Linux kernel's KVM     hypervisor handled exceptions delivered after a stack     switch operation via Mov SS or Pop SS instructions.
    During the stack switch operation, the processor did     not deliver interrupts and exceptions, rather they are     delivered once the first instruction after the stack     switch is executed. An unprivileged KVM guest user     could use this flaw to crash the guest or, potentially,     escalate their privileges in the guest.

  - 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. NOTE:
    This fix also requires CPU microcode/firmware updates     and subscribers are advised to contact their hardware     OEM vendors to receive the appropriate     microcode/firmware for their processor. A kernel     update, without the appropriate firmware/microcode     updated for the processor, is insufficient to remediate     this vulnerability.

  - A flaw was found in the way the Linux kernel handled     exceptions delivered after a stack switch operation via     Mov SS or Pop SS instructions. During the stack switch     operation, the processor did not deliver interrupts and     exceptions, rather they are delivered once the first     instruction after the stack switch is executed. An     unprivileged system user could use this flaw to crash     the system kernel resulting in the denial of service.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
