[cups.bugs] [HIGH] STR #1576: cups_local_auth() will crash for domain sockets

[Michael Hofmann]

[STR New]

cups_local_auth() in cups/auth.c will crash for domain sockets. It uses
httpAddrLocalhost(http->hostaddr) to look for localhost. A domain socket
will have http->hostaddr=null, which is not tested in httpAddrLocalhost().

I've only tested this with the KDE cups interface code which uses a direct
copy of this function.
