VMSA-2016-0002 : VMware product updates address a critical glibc security vulnerability

high Nessus Plugin ID 88954

Language:

Synopsis

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

Description

a. glibc update for multiple products.

 The glibc library has been updated in multiple products to resolve a stack-based 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 categories :
 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.
 ESXi 5.5 and ESXi 6.0 ship with a vulnerable version of glibc and are affected. 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. WORKAROUND

 Workarounds are available for several virtual appliances. These are documented in VMware KB article 2144032.

 RECOMMENDATIONS

 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 available.

 Table 1 - ESXi ==============

Solution

Apply the missing patch.
