[Bug 1348332] [NEW] sulogin crashes if root password is "x"

 

Public bug reported:

There is no check for the pointer return value of library call crypt()
before the pointer is used by strcmp().  This results in a segmentation
fault and prevents the maintenance shell from running at system start-up
if there is a problem mounting one or more filesystems.
