Description (partial)

Cisco NX-OS based devices utilize the Linux Pluggable Authentication Modules (PAM) for authentication to the device.  The PAM configuration files are not accessible from the user interface of 
the device and should be properly hardened to ensure unauthorized modification can not be done if a user was to break out of the user interface.  This bug documents changing the file 
permissions on these files to more secure defaults.

Devices running an affected version of Cisco NX-OS software.
