CVE-2016-0634

Name of the Vulnerable Software and Affected Versions bash version 4.3

Description The issue allows remote authenticated users to execute arbitrary code via shell metacharacters placed in 'hostname' of a machine, due to the expansion of 'h' in the prompt string.

Recommendations For bash version 4.3, consider restricting access to the vulnerable hostname variable until a patch is available. As a temporary workaround, avoid using the hostname variable in the prompt string to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
