[auth-options.c auth1.c auth2.c bufaux.c buffer.h kex.c key.c packet.c] [packet.h ssh-dss.c ssh-rsa.c] Add buffer_get_cstring() and related functions that verify that the string extracted from the buffer contains no embedded \0 characters* This prevents random (possibly malicious) crap from being appended to strings where it would not be noticed if the string is used with a string(3) function. Use the new API in a few sensitive places. * actually, we allow a single one at the end of the string for now because we don't know how many deployed implementations get this wrong, but don't count on this to remain indefinitely.
