"According to the version of the gcc packages installed, the EulerOS
Virtualization for ARM 64 installation on the remote host is affected
by the following vulnerability :

  - This is compiler for arm64. Security Fix(es):The POWER9
    backend in GNU Compiler Collection (GCC) before version
    10 could optimize multiple calls of the __builtin_darn
    intrinsic into a single call, thus reducing the entropy
    of the random number generator. This occurred because a
    volatile operation was not specified. For example,
    within a single execution of a program, the output of
    every __builtin_darn() call may be the
    same.(CVE-2019-15847)

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.");
