Release Notes for Samba 3.6.25
February 23, 2015
==============================
This is a security release in order to address CVE-2015-0240 (Unexpected
code execution in smbd).
o CVE-2015-0240:
All versions of Samba from 3.5.0 to 4.2.0rc4 are vulnerable to an
unexpected code execution vulnerability in the smbd file server
daemon.
A malicious client could send packets that may set up the stack in
such a way that the freeing of memory in a subsequent anonymous
netlogon packet could allow execution of arbitrary code. This code
would execute with root privileges.
o CVE-2014-0178:
In preparing a response to an authenticated FSCTL_GET_SHADOW_COPY_DATA
or FSCTL_SRV_ENUMERATE_SNAPSHOTS client request, affected versions of
Samba do not initialize 8 bytes of the 16 byte SRV_SNAPSHOT_ARRAY
response field. The uninitialized buffer is sent back to the client.
A non-default VFS module providing the get_shadow_copy_data_fn() hook
must be explicitly enabled for Samba to process the aforementioned
client requests. Therefore, only configurations with "shadow_copy" or
"shadow_copy2" specified for the "vfs objects" parameter are vulnerable.

Release Notes for Samba 3.6.24
June 23, 2014
==============================
This is a security release in order to address
CVE-2014-0244 (Denial of service - CPU loop) and
CVE-2014-3493 (Denial of service - Server crash/memory corruption).
o CVE-2014-0244:
All current released versions of Samba are vulnerable to a denial of
service on the nmbd NetBIOS name services daemon. A malformed packet
can cause the nmbd server to loop the CPU and prevent any further
NetBIOS name service.
This flaw is not exploitable beyond causing the code to loop expending
CPU resources.
o CVE-2014-3493:
All current released versions of Samba are affected by a denial of service
crash involving overwriting memory on an authenticated connection to the
smbd file server.

Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.

Release Notes for Samba 3.6.23
March 11, 2014
==============================
This is a security release in order to address
CVE-2013-4496 (Password lockout not enforced for SAMR password changes).
o CVE-2013-4496:
Samba versions 3.4.0 and above allow the administrator to implement
locking out Samba accounts after a number of bad password attempts.
However, all released versions of Samba did not implement this check for
password changes, such as are available over multiple SAMR and RAP
interfaces, allowing password guessing attacks.
|
|
not use libtool to do so. This is required to correctly depend upon a
gcc runtime package (e.g. gcc47-libs) when using USE_PKGSRC_GCC_RUNTIME.
|
|
These are now handled dynamically if INIT_SYSTEM is set to "rc.d", or
ignored otherwise.
|
|
Bump PKGREVISION.

Release Notes for Samba 3.6.17
August 05, 2013
==============================
This is a security release in order to address
CVE-2013-4124 (Missing integer wrap protection in EA list reading can cause
server to loop with DOS).
o CVE-2013-4124:
All current released versions of Samba are vulnerable to a denial of
service on an authenticated or guest connection. A malformed packet
can cause the smbd server to loop the CPU performing memory
allocations and preventing any further service.
A connection to a file share, or a local account is needed to exploit
this problem, either authenticated or unauthenticated if guest
connections are allowed.
This flaw is not exploitable beyond causing the code to loop
allocating memory, which may cause the machine to exceed memory
limits.
Changes since 3.6.16:
---------------------
o Jeremy Allison <jra@samba.org>
* BUG 10010: CVE-2013-4124: Missing integer wrap protection in EA list
reading can cause server to loop with DOS.

Release Notes for Samba 3.6.12
January 30, 2013
==============================
This is a security release in order to address
CVE-2013-0213 (Clickjacking issue in SWAT) and
CVE-2013-0214 (Potential XSRF in SWAT).
o CVE-2013-0213:
All current released versions of Samba are vulnerable to clickjacking in the
Samba Web Administration Tool (SWAT). When the SWAT pages are integrated into
a malicious web page via a frame or iframe and then overlaid by other content,
an attacker could trick an administrator to potentially change Samba settings.
In order to be vulnerable, SWAT must have been installed and enabled
either as a standalone server launched from inetd or xinetd, or as a
CGI plugin to Apache. If SWAT has not been installed or enabled (which
is the default install state for Samba) this advisory can be ignored.
o CVE-2013-0214:
All current released versions of Samba are vulnerable to a cross-site
request forgery in the Samba Web Administration Tool (SWAT). By guessing a
user's password and then tricking a user who is authenticated with SWAT into
clicking a manipulated URL on a different web page, it is possible to manipulate
SWAT.
In order to be vulnerable, the attacker needs to know the victim's password.
Additionally SWAT must have been installed and enabled either as a standalone
server launched from inetd or xinetd, or as a CGI plugin to Apache. If SWAT has
not been installed or enabled (which is the default install state for Samba)
this advisory can be ignored.
Changes since 3.6.11:
--------------------
o Kai Blin <kai@samba.org>
* BUG 9576: CVE-2013-0213: Fix clickjacking issue in SWAT.
* BUG 9577: CVE-2013-0214: Fix potential XSRF in SWAT.

1) Move the INSTALL_TEMPLATES line to the 'winbind' option section.
2) Enable the install script on all platforms.
3) Use the value of ${NSS_WINBIND} in the script as the name of the
library (should work on all platforms).
4) In the install script only create the symlink if ${NSS_WINBIND} doesn't
start with '@comment' (i.e. no nss winbind on this platform) and the
target file exists and the symlink _doesn't_ already exist.
5) Create a DEINSTALL_TEMPLATES to remove the nss winbind symlink if it
exists and point to the correct target.
Bump PKGREVISION.
