The remote VMware ESXi host is version 5.1 prior to build 2323231. It is, therefore, affected by the following vulnerabilities in the glibc library :
A buffer overflow flaw exists in the ‘extend_buffers’ function of the ‘posix/regexec.c’ file due to improper validation of user input. Using a specially crafted expression, a remote attacker can cause a denial of service. (CVE-2013-0242)
A buffer overflow flaw exists in the ‘getaddrinfo’ function of the ‘/sysdeps/posix/getaddrinfo.c’ file due to improper validation of user input. A remote attacker can cause a denial of service by triggering a large number of domain conversions. (CVE-2013-1914)
