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

  - The allocate_elf function in common.h in elfutils
    before 0.168 allows remote attackers to cause a denial
    of service (crash) via a crafted ELF file, which
    triggers a memory allocation failure.(CVE-2016-10254)

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.");
