Introduction

You are running Debian stable, because you prefer the Debian stable tree. It runs great, there is just one problem: the software is a little bit outdated compared to other distributions. This is where backports come in.

Backports are packages taken from the next Debian release (called "testing"), adjusted and recompiled for usage on Debian stable. Because the package is also present in the next Debian release, you can easily upgrade your stable+backports system once the next Debian release comes out. (In a few cases, usually for security updates, backports are also created from the Debian unstable distribution.)

Backports cannot be tested as extensively as Debian stable, and backports are provided on an as-is basis, with risk of incompatibilities with other components in Debian stable. Use with care!

It is therefore recommended to only select single backported packages that fit your needs, and not use all available backports.

Where to start

News

Thomas Goirand uploaded new packages for horizon which fixed the
following security problem:

CVE-2015-3988:
  Sunil Yadav from IBM Security Services reported a persistent XSS in
  Horizon. An authenticated user may conduct a persistent XSS attack by
  setting a malicious metadata to a Glance image, a Nova flavor or a
  Host Aggregate and tricking an administrator to load the update
  metadata page. Once executed in a legitimate context this attack may
  result in a privilege escalation.

For the jessie-backports distribution the problems have been fixed in
2015.1.0-2~bpo8+1.

Wouter Verhelst uploaded new packages for nbd which fixed the following
security problems:

CVE-2015-0847
  Tuomas Räsänen discovered that nbd-server unsafe signal handling in
  nbd-server, the server for the Network Block Device protocol, could
  allow remote attackers to cause a deadlock in the server process and
  thus a denial of service.

CVE-2013-7441
  Tuomas Räsänen discovered that the modern-style negotiation was
  carried out in the main process before forking the actual client
  handler. This could allow a remote attacker to cause a denial of
  service (crash) by querying a non-existent export.

For the squeeze-backports distribution,the problems have been fixed in
version 1:3.2-4~deb7u5~bpo60+1.

The wheezy-backports and jessie-backports suites do not contain nbd
packages, and therefore are not vulnerable (but see DSA-3271-1).

Rene Engelhard uploaded new packages for libreoffice which fixed the
following security problem:

CVE-2015-1774:
   It was discovered that missing input sanitising in Libreoffice's filter
   for HWP documents may result in the execution of arbitrary code if a
   malformed document is opened.

For the squeeze-backports distribution the problem has been fixed in
version 1:3.5.4+dfsg2-0deb7u4~bpo60+1.

For the wheezy-backports distribution the problem has been fixed in
version 1:4.3.3-2+deb8u1~bpo70+1.

      Dear users of the backports service!

 With the release of Jessie (coming up) we are pleased to open the doors
for jessie-backports and wheezy-backports-sloppy (mostly all
architectures are already buildable there, too).  Whee!

 But, PLEASE DO READ ON, there are some changes in the process that we
would like to do for the new upload pockets.


== What to upload where ==

 As a reminder, uploads to a release-backports pocket are to be taken
from release + 1, uploads to a release-backports-sloppy pocket are to be
taken from release + 2.  Which means:

 Source Distribution | Backports Distribution | Sloppy Distribution
---------------------|------------------------|--------------------------
 stretch             | jessie-backports       | wheezy-backports-sloppy
 jessie              | wheezy-backports       | squeeze-backports-sloppy


== We drop -v switch hard requirement ==

 We required uploads to contain the changelog entries since the former
version in stable in the changes file.  This was quite convenient for
people reading the changes through the changes mailinglist but
especially also for the backports team when processing packages.

 Given that the changelogs of former backports and the packages
backported are available through the packages.debian.org website
(amongst other sources) and that it was annoying to both backporters and
also us as backports team we are dropping it as hard requirement.  It
would still be pretty awesome for the above mentioned reasons if you
could keep it as part of your workflow, especially for uploads that end
in the policy queue, but we won't reject packages based solely on that
nymore.


== Versioning ==

 Previous we used ~bpo70+1 as suffix for the versions of uploads.  We
were asked whether we might want to align that with the other suffixes
used and drop the zero from within there, and yes, we will drop it.
This means that uploads to jessie-backports should use ~bpo8+1 as
suffix, and also wheezy-backports-sloppy uses ~bpo7+1 as suffix.

 For wheezy-backports please still use ~bpo70+1 version suffixes
because of sorting reasoning, especially if there are also
squeeze-backports-sloppy packages around.  Which brings us to ...


== squeeze-backports* ==

 As you are probably aware, squeeze is still a supported release through
LTS.  The same goes for the squeeze-backports* suites, you can consider
them to be around for the same timeframe that LTS is going to be around.


== Statistics ==

 For packages backported from jessie, so far we have 995 different
source packages in wheezy-backports, and 27 different source packages in
squeeze-backports-sloppy.  Those 995 source packages took 1729 uploads
to become reality.


== Thanks ==

 Thanks have to go out to all people making backports possible, and that
includes up front the backporters themself who do upload the packages,
track and update them on a regular basis, but also the buildd team
making the autobuilding possible and the ftp masters for creating the
suites in the first place.

 Enjoy, and continue being awesome!
Rhonda, on behalf of the Backports Team

Rene Engelhard uploaded new packages for libreoffice which fixed the
following security problems:

CVE-2014-3693:
   Use-After-Free in socket manager of Impress Remote

   It was discovered that LibreOffice 4.0.0 and later does not manage the port
   1599 for the LibreOffice Impress correctly. An external attackers with
   access to that port could cause the deleted port manager to continue to
   process attacker supplied data.

Note that this update also disables the remote contol per default as it
listens on port 1599 "to the world" per default. If you want/need it you
need to enable it manally:
   1. Open LibreOffice, go to "Tools -> Options..."
   2. Select "LibreOffice Impress -> General"
   3. Check "Presentation -> Enable remote control"

For the wheezy-backports distribution the problems have been fixed in
version 1:4.3.3~rc2-1~bpo70+1.
