[Samba] 3.0.21c safe_strcat string overflow w/ "net rpc share migrate files"

[Thomas Limoncelli]

When migrating files off an existing Win2K file server using "net rpc 
share migrate files" with Samba 3.0.21c on SuSE 9.3 Pro I stumbled 
across a number of "string overflow by X in safe_strcat" errors on a few 
files with non-ASCII characters:

myserver# net rpc share migrate files myshare --acls --attrs 
--timestamps -S win2k -U 'XXX\administrator' --destination=`hostname`
Password:
syncing    [myshare] files and directories including ACLs, including DOS 
Attributes (preserving timestamps)

   ERROR: string overflow by 4 in safe_strcat [Meyer ABCD Ostlandstr., 
Carl-Köttgen-Str., Pe]

Also, there are a number of (possibly related) errors of the kind:

could not handle file: \some\long\path\with\special\characters\like 
öüäß: NT_STATUS_OBJECT_NAME_NOT_FOUND


Would this likely be a Samba or W2K server bug? Is there any way to 
migrate these files using any sort of automated mangling? I'm willing to 
provide level 10 debug logs, Ethereal traces and whatever it may take to 
track it down.
