According to the version of the libidn package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

  - The stringprep_utf8_to_ucs4 function in libin before     1.31, as used in jabberd2, allows context-dependent     attackers to read system memory and possibly have other     unspecified impact via invalid UTF-8 characters in a     string, which triggers an out-of-bounds     read.(CVE-2015-2059)

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.
