> Changes in 2.2.1
> -----------------
>
> 1). "find" command removed for smbclient. Internal code now used.
> 2). smbspool updates to retry connections from Michael Sweet.
> 3). Fix for mapping 8859-15 characters to UNICODE.
> 4). Changed "security=server" to try with invalid username to prevent

> SECURITY FIX
> ============
>
> This is a security bugfix release for Samba 2.2.0. This release provides the
> following two changes *ONLY* from the 2.2.0 release.
>
> 1). Fix for the security hole discovered by Michal Zalewski ([email protected])
>     and described in the security advisory below.
> 2). Fix for the hosts allow/hosts deny parameters not being honoured.
>
> No other changes are being made for this release to ensure a security fix only.
> For new functionality (including these security fixes) download Samba 2.2.1

>                 IMPORTANT: Security bugfix for Samba
>                 ------------------------------------
>
> June 23rd 2001
>
>
> Summary
> -------
>
> A serious security hole has been discovered in all versions of Samba
> that allows an attacker to gain root access on the target machine for
> certain types of common Samba configuration.
>
> The immediate fix is to edit your smb.conf configuration file and
> remove all occurances of the macro "%m". Replacing occurances of %m
> with %I is probably the best solution for most sites.
>
> Details
> -------
>
> A remote attacker can use a netbios name containing unix path
> characters which will then be substituted into the %m macro wherever
> it occurs in smb.conf. This can be used to cause Samba to create a log
> file on top of an important system file, which in turn can be used to
> compromise security on the server.
>
> The most commonly used configuration option that can be vulnerable to
> this attack is the "log file" option. The default value for this
> option is VARDIR/log.smbd. If the default is used then Samba is not
> vulnerable to this attack.
>
> The security hole occurs when a log file option like the following is
> used:
>
>   log file = /var/log/samba/%m.log
>
> In that case the attacker can use a locally created symbolic link to
> overwrite any file on the system. This requires local access to the
> server.
>
> If your Samba configuration has something like the following:
>
>   log file = /var/log/samba/%m
>
> Then the attacker could successfully compromise your server remotely
> as no symbolic link is required. This type of configuration is very
> rare.
>
> The most commonly used log file configuration containing %m is the
> distributed in the sample configuration file that comes with Samba:
>
>   log file = /var/log/samba/log.%m
>
> in that case your machine is not vulnerable to this attack unless you
> happen to have a subdirectory in /var/log/samba/ which starts with the
> prefix "log."
>
> Credit
> ------
>
> Thanks to Michal Zalewski ([email protected]) for finding this
> vulnerability.
>
>
> New Release
> -----------
>
> While we recommend that vulnerable sites immediately change their
> smb.conf configuration file to prevent the attack we will also be
> making new releases of Samba within the next 24 hours to properly fix
> the problem. Please see http://www.samba.org/ for the new releases.
>
> Please report any attacks to the appropriate authority.

> ---------------------------------------------------------------------------
>
> The release notes for 2.2.0 follow :
>
> This is the official Samba 2.2.0 release. This version of Samba provides
> the following new features and enhancements.
>
> Integration between Windows oplocks and NFS file opens (IRIX and Linux
> 2.4 kernel only). This gives complete data and locking integrity between
> Windows and UNIX file access to the same data files.
>
> Ability to act as an authentication source for Windows 2000 clients as
> well as for NT4.x clients.
>
> Integration with the winbind daemon that provides a single
> sign on facility for UNIX servers in Windows 2000/NT4 networks
> driven by a Windows 2000/NT4 PDC. winbind is not included in
> this release, it currently must be obtained separately. We are
> committed to including winbind in a future Samba 2.2.x release.
>
> Support for native Windows 2000/NT4 printing RPCs. This includes
> support for automatic printer driver download.
>
> Support for server supported Access Control Lists (ACLs).
> This release contains support for the following filesystems:
>
>     Solaris 2.6+
>     SGI Irix
>     Linux Kernel with ACL patch from http://acl.bestbits.at
> 	Linux Kernel with XFS ACL support.
> 	Caldera/SCO UnixWare
> 	IBM AIX
> 	FreeBSD (with external patch)
>
> Other platforms will be supported as resources are
> available to test and implement the necessary modules. If
> you are interested in writing the support for a particular
> ACL filesystem, please join the samba-technical mailing
> list and coordinate your efforts.
>
> On PAM (Pluggable Authentication Module) based systems - better debugging
> messages and encrypted password users now have access control verified via
> PAM - Note: Authentication still uses the encrypted password database.
>
> Rewritten internal locking semantics for more robustness.
> This release supports full 64 bit locking semantics on all
> (even 32 bit) platforms. SMB locks are mapped onto POSIX
> locks (32 bit or 64 bit) as the underlying system allows.
>
> Conversion of various internal flat data structures to use
> database records for increased performance and
> flexibility.
>
> Support for acting as a MS-DFS (Distributed File System) server.
>
> Support for manipulating Samba shares using Windows client tools
> (server manager). Per share security can be set using these tools
> and Samba will obey the access restrictions applied.
>
> Samba profiling support (see below).
>
> Compile time option for enabling a (Virtual file system) VFS layer
> to allow non-disk resources to be exported as Windows filesystems
> (such as databases etc.).
>
> The documentation in this release has been updated and converted
> from Yodl to DocBook 4.1. There are many new parameters since 2.0.7
> and some defaults have changed.
>
> Profiling support.
> ------------------
> Support for collection of profile information. A shared
> memory area has been created which contains counters for
> the number of calls to and the amount of time spent in
> various system calls, smb transactions and nmbd activity. See
> the file profile.h for a complete listing of the information
> collected. Sample code for a samba pmda (collection agent
> for Performance Co-Pilot) has been included in the pcp
> directory.
>
> To enable the profile data collection code in samba, you must
> compile samba with profile data support (run configure with
> the --with-profiling-data option). On startup, collection of
> data is disabled. To begin collecting data use the smbcontrol
> program to turn on profiling (see the smbcontrol man page).
> Profile information collection can be enabled for nmbd, all smbd
> processes or one or more selected processes. The profiling
> data collected is the aggregate for all processes that have
> profiling enabled.
>
> With samba compiled for profile data collection, you may see
> a very slight degradation in performance even with profiling
> collection turned off. On initial tests with NetBench on an
> SGI Origin 200 server, this degradation was not measurable
> with profile collection off compared to no profile collection
> compiled into samba.
>
> With count profile collection enabled on all clients, the
> degradation was less than 2%. With full profile collection
> enabled on all clients, the degradation was about 8.5%.
