Bits from the Testing Security team

We finally got around to sending this email to inform you about the
current state of the Testing Security team and its work.
Hi fellow developers,

We finally got around to sending this email to inform you about the
current state of the Testing Security team and its work.

If you at any stage have questions about the Testing Security team,
please feel free to come to #debian-security on OFTC or write an email
to secure-testing-team@lists.alioth.debian.org .

Security status of testing
————————–

Thanks to an increased size of our team, Debian Lenny is in good shape
with respect to security and has been so for some time. We expect to be
able to keep up this level of security support (at least) until the
release of Lenny.

In the weeks immediately after the release of Etch there were some
security support problems for testing. We hope to improve our processes
so that we won't run into the same problems after the release of Lenny.
There will be another announcement about the state of these efforts well
before Lenny's release.

Our web page[0] has been updated to reflect the current status.

New announcement mails
———————-

Previously we were mimicing the announcement method that Stable security
uses by providing DTSAs (Debian Testing Security Advisories). However,
these were only prepared for issues that required us to manually prepare
package updates, thereby forcing a package into testing that would not
otherwise migrate automatically in a reasonable time-frame. This
resulted in very infrequent DTSAs because most of the security issues
were dealt with by fixed packages migrating from unstable to testing.

Therefore, we set up daily announcements (delivered to the announcement
mailinglist[1]), which include all new security fixes for the testing
distribution. Most commonly the email shows the migrated packages. If
there has been a DTSA issued for a package, this will show up as well.

In some rare cases, the Testing Security team asks the release managers
to remove a package from testing, because a security fix in a reasonable
amount of time seems to be unlikely and the package should not be part
of testing in our opinion. In this case, the email will additionally
include information about the removal.

Efforts to fix security issues in unstable
——————————————

The Testing Security team works mainly on assigned CVE numbers but also
follows security relevant bugs reported via the BTS. If you encounter a
security problem in one of your packages, which does not have a CVE
number yet, please contact the Testing Security team. It is important
to have a CVE id allocated, because they allow us to track the security
problem in all Debian branches (including Debian stable). When you
upload a security fix to unstable, please also include the CVE id in
your changelog and set the urgency to high. The tracker used by both the
Testing and Stable Security teams, can be found on this webpage[2].

The main task of the Testing Security team is to review CVE id relevance
to Debian, informing Debian maintainers by filing bugs to the BTS (if
not already done) and chasing the security fix to move it faster into
testing. Whenever possible, we try to provide patches and sometimes
also NMU the packages in unstable. Please do not regard an NMU by the
Testing Security team as a bad sign. We try to assist you in the best
way to keep Debian secure. Also keep in mind that not all security
related problems have a grave severity, so do not be surprised if a
normal bug in the Debian BTS results in assigning a CVE id for it. An
up to date overview of unresolved issues in unstable can be found on the
tracker website[3].

Efforts to fix security issues in testing
—————————————–

Our efforts to keep testing secure are primarily focused around letting
fixed packages migrate from unstable. In order to ensure this migration
process, we are in close contact with the release team and request
priority bumps to speed up the migration. Sometimes a package is kept
from migrating due to a transition, the occurrence of new bugs in
unstable, buildd issues or other problems. In these cases, the Testing
Security team considers the possibility of issuing a DTSA. We always
appreciate it when the maintainer contacts us about their specific
security problem. When we are in communication then we can assist by
telling you whether to wait for migration or to prepare an upload to
testing-security. For non-DDs, these uploads can be sponsored by every
DD, preferable by a member of the Testing Security team. If you get a go
for an upload to testing-security by one of us, please follow the
guidelines on the webpage[4]. If we feel the need to issue a DTSA and
were not contacted by the maintainer, we normally go ahead and upload
ourselves, although efforts by maintainer to be involved in this process
is much preferred.

An up to date overview of unresolved issues in testing can be found on
the tracker website[5].

Embedded code copies
——————–

There are a number of packages including source code from external
libraries, for example poppler is included in xpdf, kpdf and others. To
ensure that we don't miss any vulnerabilities in packages that do so we
maintain a list[6] of embedded code copies in Debian. It is preferable
that you do not embed copies of code in your packages, but instead link
against packages that already exist in the archive. Please contact us
about any missing items you know about.

Some statistics
—————

* 35 DTSAs had been issued in 2007 so far for over 139 CVE ids
* 39 NMUs were uploaded in the last two months to fix security flaws
* 49 security related uploads migrated to testing in the last month
for 71 CVE ids
* 5500 CVE ids had been processed by the team so far for this year

New Testing Security Members
—————————-

New members are constantly added to the team. The most recent additions
are Nico Golde, Steffen Joeris, and Thijs Kinkhorst. The circle of team
members who may approve releases to the testing-security repository has
also been enlarged by Stefan Fritsch (since May), Nico Golde and Steffen
Joeris (both added recently).

If you are interested in joining the team, we always need more people,
and it's not very hard to contribute in very small ways that have large
impacts! Contact us if you are interested. You may want to also look at
our helping page[7].

So far so good. We hope to keep you updated on testing security issues
more regularly.

Yours,
Testing Security team
