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

  • inftrees.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact by leveraging improper pointer arithmetic.(CVE-2016-9840)

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.
