"According to the versions of the elfutils packages installed, the
EulerOS Virtualization for ARM 64 installation on the remote host is
affected by the following vulnerabilities :

  - libdw in elfutils 0.173 checks the end of the
    attributes list incorrectly in dwarf_getabbrev in
    dwarf_getabbrev.c and dwarf_hasattr in dwarf_hasattr.c,
    leading to a heap-based buffer over-read and an
    application crash.(CVE-2018-16403)

  - libelf/elf_end.c in elfutils 0.173 allows remote
    attackers to cause a denial of service (double free and
    application crash) or possibly have unspecified other
    impact because it tries to decompress
    twice.(CVE-2018-16402)

  - dwarf_getaranges in dwarf_getaranges.c in libdw in
    elfutils before 2018-08-18 allows remote attackers to
    cause a denial of service (heap-based buffer over-read)
    via a crafted file.(CVE-2018-16062)

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.");
