The remote VMware ESXi host is version 5.5 prior to build 1623387. It is, therefore, affected by multiple vulnerabilities :
Multiple integer overflow conditions exist in the bundled GNU C Library (glibc) due to improper validation of user-supplied input. A remote attacker can exploit these issues to cause a buffer overflow, resulting in a denial of service condition. (CVE-2013-4332)
A flaw exists in the monlist feature in NTP. A remote attacker can exploit this flaw, using a specially crafted packet to load the query function in monlist, to conduct a distributed denial of service attack.
(CVE-2013-5211)
