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

  - The gcc package contains the GNU Compiler Collection
    version 4.8.You'll need this package in order to
    compile C code.Security Fix(es):The demangle_template
    function in cplus-dem.c in GNU libiberty, as
    distributed in GNU Binutils 2.31.1, has a memory leak
    via a crafted string, leading to a denial of service
    (memory consumption), as demonstrated by cxxfilt, a
    related issue to CVE-2018-12698.(CVE-2018-20657)

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.");
