VMware ESXi Multiple DoS (VMSA-2014-0008)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote VMware ESXi host is missing a security-related patch.

Description :

The remote ESXi host is affected by multiple denial of service
vulnerabilities in the glibc library :

- A buffer overflow condition exists in the
extend_buffers() function in file posix/regexec.c due to
improper validation of user-supplied input when handling
multibyte characters in a regular expression. An
unauthenticated, remote attacker can exploit this, via
a crafted regular expression, to corrupt the memory,
resulting in a denial of service. (CVE-2013-0242)

- A stack-based buffer overflow condition exists in the
getaddrinfo() function in file posix/getaddrinfo.c due
to improper validation of user-supplied input during the
handling of domain conversion results. An
unauthenticated, remote attacker can exploit this to
cause a denial of service by using a crafted host name
or IP address that triggers a large number of domain
conversion results. (CVE-2013-1914)
