Subject: CVE Request: FreeBSD kernel, double-fetch bug in smb_strdupin


In function  smb_strdupin()  of file sys/netsmb/smb_subr.c,
smb_strdupin() tried to roll a copyin() based strlen to allocate a buffer
and then blindly copyin that size.  Of course, a malicious user program
could simultaneously manipulate the buffer, resulting in a non-terminated
string being copied.

Bug report:

Please help assign a CVE to it.
