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

  - It was discovered that the snmp_pdu_parse() mishandles
    error codes and is vulnerable to a heap corruption
    within the parsing of the PDU prior to the
    authentication process. A remote, unauthenticated
    attacker could use this flaw to crash snmpd or,
    potentially, execute arbitrary code on the system with
    the privileges of the user running
    snmpd.(CVE-2018-1000116)

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.");
