"According to the version of the parallels-server-bm-release /
vzkernel / etc packages installed, the Virtuozzo installation on the
remote host is affected by the following vulnerability :
- 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 that Tenable Network Security has extracted the preceding
description block directly from the Virtuozzo security advisory.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues.");
