== Subject: Remote code execution in Samba's WINS
== server daemon (nmbd) when processing name
== registration followed name query requests.

== CVE ID#: CVE-2007-5398
==
== Versions: Samba 3.0.0 - 3.0.26a (inclusive)
...
Secunia Research reported a vulnerability that allows for
the execution of arbitrary code in nmbd. This defect may
only be exploited when the "wins support" parameter has
been enabled in smb.conf.
(This used to be commit e40c372e0ddf631dd9162c1fdfaaa49c29915f23)
to struct sockaddr_storage in most places that matter (ie.
not the nmbd and NetBIOS lookups). This passes make test
on an IPv4 box, but I'll have to do more work/testing on
IPv6 enabled boxes. This should now give us a framework
for testing and finishing the IPv6 migration. It's at
the state where someone with a working IPv6 setup should
(theorecically) be able to type :
smbclient //ipv6-address/share
and have it work.

bugs in various places whilst doing this (places that assumed
BOOL == int). I also need to fix the Samba4 pidl generation
(next checkin).

IPv6 in winbindd, but moves most of the socket functions that were
wrongly in lib/util.c into lib/util_sock.c and provides generic
IPv4/6 independent versions of most things. Still lots of work
to do, but now I can see how I'll fix the access check code.
Nasty part that remains is the name resolution code which is
used to returning arrays of in_addr structs.
Jeremy.
(This used to be commit 3f6bd0e1ec5cc6670f3d08f76fc2cd94c9cd1a08)
the ripple effects this causes. utmp has to change etc. Remove some
global varables and store address/port in the unexpected db.
Jeremy.
(This used to be commit 18c6a2211d9e25233d01715b3f78977edcd6d869)
to all callers of smb_setlen (via set_message()
calls). This will allow the server to reflect back
the correct encryption context.
Jeremy.
(This used to be commit 2d80a96120a5fe2fe726f00746d36d85044c4bdb)
* \PIPE\unixinfo
* winbindd's {group,alias}membership new functions
* winbindd's lookupsids() functionality
* swat (trunk changes to be reverted as per discussion with Deryck)
(This used to be commit 939c3cb5d78e3a2236209b296aa8aba8bdce32d3)
use the correct RR type of 0xA instead of reflecting back what
the query RR type was (0x20). See rfc1002 sections 4.2.14 and
4.2.16.
Jeremy.
(This used to be commit ab8c9240044f1ef3d5c6ac4850c8ec615c2e32fd)
functions so we can funnel through some well known functions. Should help greatly with
malloc checking.
HEAD patch to follow.

(This used to be commit 620f2e608f70ba92f032720c031283d295c5c06a)
names in nmbd. Allows conversion from dos codepage mb strings (ie. SJIS) to
expand to utf8 size on read.
Jeremy.
(This used to be commit 834d816caf9cd6318da00febde50d9233469dac2)
Don't use nstrings to hold workgroup and netbios names. The problem with them is that MB netbios
and workgroup names in unix charset (particularly utf8) may be up to 3x bigger than the name
when represented in dos charset (ie. cp932). So go back to using fstrings for these but
translate into nstrings (ie. 16 byte length values) for transport on the wire.
Jeremy.
(This used to be commit b4ea493599ab414f7828b83f40a5a8b43479ff64)
iconv wasn't re-initialised on reading of "charset" parameters. This
caused workgroup name to be set incorrectly if it contained an
extended character.
Jeremy.
(This used to be commit 84ae44678a6c59c999bc1023fdd9b7ad87f4ec18)
dashes of const. This is a rather large check-in, some things may break.
It does compile though :-).
Jeremy.
(This used to be commit f755711df8f74f9b8e8c1a2b0d07d02a931eeb89)
processing work correctly in winbindd. This is a really good patch
that gives full select semantics to the Samba modified select.
Jeremy.
(This used to be commit 3af16ade173cac24c1ac5eff4a36b439f16ac036)
the DGRAM_PORT, since we want to actually send those to other ports.
They might be for the client library running on the Samba server!
(This used to be commit 05e2dd5e85d4aca1ccb9f6991e1415f85cbbdc1a)
easier to add new message types to messages.h without breaking old
binaries
- added a MSG_FORCE_ELECTION message to force nmbd to hold an election
(This used to be commit f1c49ca7ce56bc39259041a71479e84ebf53eeca)
