"According to the version of the dracut packages installed, the
EulerOS 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 instructions (a commonly used performance
optimization). There are three primary variants of the
issue which differ in the way the speculative execution
can be exploited. Variant CVE-2017-5715 triggers the
speculative execution by utilizing branch target
injection. It relies on the presence of a
precisely-defined instruction sequence in the
privileged code as well as the fact that memory
accesses may cause allocation 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 cross the
syscall and guest/host boundaries and read privileged
memory by conducting targeted cache side-channel
attacks.(CVE-2017-5715)
Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
