My Free Software Activities in January 2017

by

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donors (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

I was allocated 10 hours to work on security updates for Debian 7 Wheezy. During this time I did the following:

  • I reviewed multiple CVE affecting ntp and opted to mark them no-dsa (just like what has been done for jessie).
  • I pinged upstream authors of jbig2dec (here) and XML::Twig (by private email) where the upstream report had not gotten any upstream reply yet.
  • I asked on oss-security for more details about CVE-2016-9584 because it was not clear whether it had already been reported upstream. Turns out that it was. I then updated the security tracker accordingly.
  • Once I got a reply on jbig2dec, I started to backport the patch pointed out by upstream, it was hard work. When I was done, I had also received by private email the fuzzed file at the origin of the report… unfortunately that file did not trigger the same problem with the old jbig2dec version in wheezy. That said valgrind still identified read outside of allocated memory. At this point I had a closer look at the git history only to discover that the last 3 years of work consisted mainly of security fixes for similar cases that were never reported to CVE. I thus opened a discussion about how to handle this situation.
  • Matthias Geerdsen reported in #852610 a regression in libtiff4. I confirmed the problem and spent multiple hours to come up with a fix. The patch that introduced the regression was Debian-specific as upstream did not fix those issues yet. I released a fixed package in DLA-610-2.

Debian packaging

With the deep freeze approaching, I made some last-minute updates:

  • schroot 1.6.10-3 fixing some long-standing issues with the way bind mounts are shared (#761435) and other important fixes.
  • live-boot 1:20170112 to fix a failure when booting on a FAT filesystem and other small fixes.
  • live-config 5.20170112 merging useful patches from the BTS.
  • I finished the update of hashcat 3.30 with its new private library and fixed RC bug #851497 at the same time. The work was initiated by fellow members of the pkg-security team.

Misc work

Sponsorship. I sponsored a new asciidoc upload demoting a dependency into a recommends (#850301). I sponsored a new upstream version of dolibarr.

Discussions. I seconded quite a few changes prepared by Russ Allbery on debian-policy. I helped Scott Kitterman with #849584 about a misunderstanding of how the postfix service files are supposed to work. I discussed in #849913 about a regression in building of cross-compilers, and made a patch to avoid the problem. In the end, Guillem developed a better fix.

Bugs. I investigated #850236 where a django test failed during the first week after each leap year. I filed #853224 on desktop-base about multiple small problems in the maintainer scripts.

My Free Software Activities in December 2016

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donors (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

I was allocated 10 hours to work on security updates for Debian 7 Wheezy. During this time I did the following:

  • I released DLA-741-1 on unzip. This was an easy update.
  • I reviewed Roberto Sanchez’s patch for CVE-2014-9911 in ICU.
  • I released DLA-759-1 on nss in collaboration with Antoine Beaupré. I merged and updated Guido’s work to enable the testsuite during build and to add DEP-8 tests.
  • I created a git repository for php5 maintenance in Debian LTS and started to work on an update. I added patches for two CVE (CVE-2016-3141, CVE-2016-2554) and added some binary files required by (currently failing) tests.

Misc packaging

With the strong freeze approaching, I had some customer requests to push packages into Debian and/or to fix packages that were in danger of being removed from stretch.

While trying to bring back uwsgi into testing I filed #847095 (libmongoclient-dev: Should not conflict with transitional mongodb-dev) and #847207 (uwsgi: FTBFS on multiple architectures with undefined references to uwsgi_* symbols) and interacted on some of the RC bugs that were keeping the package out of testing.

I also worked on a few new packages (lua-trink-cjson, lua-inotify, lua-sandbox-extensions) that enhance hindsight in some use cases and sponsored a rozofs update in experimental to fix a file conflict with inn2 (#846571).

Misc Debian work

Debian Live. I released two live-build updates. The second update added more options to customize the grub configuration (we use it in Kali to override the theme and add more menu entries) both for EFI boot and normal boot.

Misc bugreports. #846569 on libsnmp-dev to accomodate the libssl transition (I noticed the package was not maintained, I asked for new maintainers on debian-devel). #847168 on devscripts for debuild that started failing when lintian was failing (unexpected regression). #847318 on lintian to not emit spurious errors for kali packages (which was annoying with the debuild regression above). #847436 for an upgrade problem I got with tryton-server. #847223 on firefoxdriver as it was still depending on iceweasel instead of firefox.

Sponsorship. I sponsored a new version of asciidoc (#831965) and of ssldump 0.9b3-6 (for libssl transition). I also uploaded a new version of mutter to fix #846898 (it was ready in SVN already).

Distro Tracker

Not much happening, I fixed #814315 by switching a few remaining URLs to https. I merged patches from efkin to fix the functional test suite (#814315), that was a really useful contribution! The same contributer started to tackle another ticket (#824912) about adding an API to retrieve action items. This is a larger project and needs some thoughts. I still have to respond to him on his latest patches (after two rounds already).

Misc stuff

I updated the letsencrypt-sh salt formula for version 0.3.0 and added the possibility to customize the hook script to reload the webserver.

The @planetdebian twitter account is no longer working since twitterfeed.com closed doors and the replacement (dlvr.it) is unhappy about the RSS feed of planet.debian.org. I filed bug #848123 against planet-venus since it does not preserve the isPermalink attribute in the guid tag

My Free Software Activities in November 2016

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donors (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

In the 11 hours of (paid) work I had to do, I managed to release DLA-716-1 aka tiff 4.0.2-6+deb7u8 fixing CVE-2016-9273, CVE-2016-9297 and CVE-2016-9532. It looks like this package is currently getting new CVE every month.

Then I spent quite some time to review all the entries in dla-needed.txt. I wanted to get rid of some misleading/no longer applicable comments and at the same time help Olaf who was doing LTS frontdesk work for the first time. I ended up tagging quite a few issues as no-dsa (meaning that we will do nothing for them as they are not serious enough) such as those affecting dwarfutils, dokuwiki, irssi. I dropped libass since the open CVE is disputed and was triaged as unimportant. While doing this, I fixed a bug in the bin/review-update-needed script that we use to identify entries that have not made any progress lately.

Then I claimed libgc and and released DLA-721-1 aka libgc 1:7.1-9.1+deb7u1 fixing CVE-2016-9427. The patch was large and had to be manually backported as it was not applying cleanly.

The last thing I did was to test a new imagemagick and review the update prepared by Roberto.

pkg-security work

The pkg-security team is continuing its good work: I sponsored patator to get rid of a useless dependency on pycryptopp which was going to be removed from testing due to #841581. After looking at that bug, it turns out the bug was fixed in libcrypto++ 5.6.4-3 and I thus closed it.

I sponsored many uploads: polenum, acccheck, sucrack (minor updates), bbqsql (new package imported from Kali). A bit later I fixed some issues in the bbsql package that had been rejected from NEW.

I managed a few RC bugs related to the openssl 1.1 transition: I adopted sslsniff in the team and fixed #828557 by build-depending on libssl1.0-dev after having opened the proper upstream ticket. I did the same for ncrack and #844303 (upstream ticket here). Someone else took care of samdump2 but I still adopted the package in the pkg-security team as it is a security relevant package. I also made an NMU for axel and #829452 (it’s not pkg-security related but we still use it in Kali).

Misc Debian work

Django. I participated in the discussion about a change letting Django count the number of developers that use it. Such a change has privacy implications and the discussion sparked quite some interest both in Debian mailing lists and up to LWN.

On a more technical level, I uploaded version 1.8.16-1~bpo8+1 to jessie-backports (security release) and I fixed RC bug #844139 by backporting two upstream commits. This led to the 1.10.3-2 upload. I ensured that this was fixed in the 1.10.x upstream branch too.

dpkg and merged /usr. While reading debian-devel, I discovered dpkg bug #843073 that was threatening the merged-/usr feature. Since the bug was in code that I wrote a few years ago, and since Guillem was not interested in fixing it, I spent an hour to craft a relatively clean patch that Guillem could apply. Unfortunately, Guillem did not yet manage to pull out a new dpkg release with the patches applied. Hopefully it won’t be too long until this happens.

Debian Live. I closed #844332 which was a request to remove live-build from Debian. While it was marked as orphaned, I was always keeping an eye on it and have been pushing small fixes to git. This time I decided to officially adopt the package within the debian-live team and work a bit more on it. I reviewed all pending patches in the BTS and pushed many changes to git. I still have some pending changes to finish to prettify the Grub menu but I plan to upload a new version really soon now.

Misc bugs filed. I filed two upstream tickets on uwsgi to help fix currently open RC bugs on the package. I filed #844583 on sbuild to support arbitrary version suffix for binary rebuild (binNMU). And I filed #845741 on xserver-xorg-video-qxl to get it fixed for the xorg 1.19 transition.

Zim. While trying to fix #834405 and update the required dependencies, I discovered that I had to update pygtkspellcheck first. Unfortunately, its package maintainer was MIA (missing in action) so I adopted it first as part of the python-modules team.

Distro Tracker. I fixed a small bug that resulted in an ugly traceback when we got queries with a non-ASCII HTTP_REFERER.

My Free Software Activities in October 2016

My monthly report covers a large part of what I have been doing in the free software world. I write it for my donors (thanks to them!) but also for the wider Debian community because it can give ideas to newcomers and it’s one of the best ways to find volunteers to work with me on projects that matter to me.

Debian LTS

Last month I started to work on tiff3 but had not enough time to complete an update, it turns out the issues were hairy enough that nobody else picked up the package. So this month I started again with tiff3 and tiff and I ended up spending my 13h on those two packages.

I filed bugs for issues that were not yet reported to the BTS (#842361 for CVE-2016-5652, #842046 for CVE-2016-5319/CVE-2016-3633/CVE-2015-8668). I marked many CVE as not affecting tiff3 as this source package does not ship the tools (the “tiff” source package does).

Since upstream decided to drop many tools instead of fixing the corresponding security issues, I opted to remove the tools as well. Before doing this, I looked up reverse dependencies of libtiff-tools to ensure that none of the tools removed are used by other packages (the maintainer seems to agree too).

I backported upstream patches for CVE-2016-6223 and CVE-2016-5652.

But the bulk of the time, I spent on CVE-2014-8128, CVE-2015-7554 and CVE-2016-5318. I believe they are all variants of the same problem and upstream seems to agree since he opened a sort of meta-bug to track them. I took inspiration from a patch suggested in ticket #2499 and generalized it a bit by trying to add the tag data for all tags manipulated by the various tools. It was a tiresome process as there are many tags used in multiple places. But in the end, it works as expected. I can no longer reproduce any of the segfaults with the problematic files.

I asked for review/test on the mailing list but did not get much feedback. I’m going to upload the updated packages soon.

Distro Tracker

I noticed a sudden raise in the number of email addresses being automatically unsubscribed from the Debian Package Tracker and I got a few request of bounces. It turns out the BTS has been relaying lots of spam with executables files and those are bounced by Google (and not silently discarded). This is all very unfortunate… the spam flood is unlikely to stop soon and I can’t expect Google to change either, so I had little choice except trying to make the bounce handler smarter. That’s what I did: I have a list of regular expression that will discard a bounce. In other words, once matched the bounce won’t count towards the limit that triggers the automatic unsubscription.

Misc Debian work

Bugs filed. In #839403, I suggest the possibility to set the default pin priority for a source in the sources.list file directly. In #840436 I ask the selenium-firefoxdriver maintainer to do what is required to get this non-free package auto-built.

Packaging. I sponsored puppet-lint 2.0.2-0.1 and I reviewed the rozofs package (wihch I just sponsored into experimental for a start).

Publicity. I’m maintaining the Debian account on Twitter and Facebook. I have been using twitterfeed.com up to now but it’s closing down. I followed their recommendations and switched to dlvr.it to automatically post entries out of the micronews.debian.org feed. In #841165, I reported that the chroots created by sbuild-createchroot are lacking the usual IPv6 entries created by netbase. In #841503, I report a very common cryptsetup upgrade failure that I saw multiple times (both in Debian and in Kali).

Thanks
