CVE

CVE-2014-6271

TITLE

GNU Bash shell executes commands in exported functions in environment variables

DESCRIPTION

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix. GNU Bash 4.3 and earlier contains a command injection vulnerability that may allow remote code execution. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. This bulletin will be revised when the updates are available. MITIGATION INFORMATION HP recommends the following steps to reduce the risk of this vulnerability: - The "ssh" or "telnet" features may be disabled by the admin user. All MDS and Nexus 5K switches can function in this configuration. Access is available through the console port. Please refer to the RESOLUTION section below for a list of impacted products.

Summary VMware product updates address Bash security vulnerabilities. 2. Relevant Releases (Affected products for which remediation is present) vCenter Log Insight 2.0 3. Problem Description a. Bash update for multiple products. Bash libraries have been updated in multiple products to resolve multiple critical security issues, also referred to as Shellshock. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifiers CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, and CVE-2014-7187 to these issues. VMware products have been grouped into the following four product categories: I) ESXi and ESX Hypervisor ESXi is not affected because ESXi uses the Ash shell (through busybox), which is not affected by the vulnerability reported for the Bash shell. ESX has an affected version of the Bash shell. See table 1 for remediation for ESX. 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 an affected version of Bash. See table 2 for remediation for appliances. IV) Products that run on Linux, Android, OSX or iOS (excluding virtual appliances) Products that run on Linux, Android, OSX or iOS (excluding virtual appliances) might use the Bash shell that is part of the operating system. If the operating system has a vulnerable version of Bash, the Bash security vulnerability might be exploited through the product. VMware recommends that customers contact their operating system vendor for a patch. MITIGATIONS VMware encourages restricting access to appliances through firewall rules and other network layer controls to only trusted IP addresses. This measure will greatly reduce any risk to these appliances. RECOMMENDATIONS VMware recommends customers evaluate and deploy patches for affected products in Table 1 and 2 below as these patches become available. 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 and ESX Hypervisor ================================= VMware Product Running Replace with/ Product Version on Apply Patch ============== ======= ======= ============= ESXi any ESXi Not affected ESX 4.1 ESX Patch pending * ESX 4.0 ESX Patch pending * * VMware will make VMware ESX 4.0 and 4.1 security patches available for the Bash shell vulnerability.
