a stack buffer overflow present in the glibc getaddrinfo function.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the identifier CVE-2015-7547.
VMware products have been grouped into the following four
I) ESXi and ESX Hypervisor
Versions of ESXi and ESX prior to 5.5 are not affected because
they do not ship with a vulnerable version of glibc.

See table 1 for remediation for ESXi 5.5 and ESXi 6.0.
II) Windows-based products
Windows-based products, including all versions of vCenter Server
running on Windows, are not affected.
III) VMware virtual appliances
VMware virtual appliances ship with a vulnerable version of glibc
and are affected.
See table 2 for remediation for appliances.
IV) Products that run on Linux
VMware products that run on Linux (excluding virtual appliances)
might use a vulnerable version of glibc as part of the base operating
system. If the operating system has a vulnerable version of glibc,
VMware recommends that customers contact their operating system
vendor for resolution.
Workarounds are available for several virtual appliances. These are
documented in VMware KB article 2144032.
VMware recommends customers evaluate and deploy patches for
affected products in Table 1 and 2 below as these patches become
available. In case patches are not available, customers are
advised to deploy the workaround.
Column 4 of the following tables lists the action required to
remediate the vulnerability in each release, if a solution is
