Free software activities in July 2018

Here is my monthly update covering what I have been doing in the free software world during July 2018 (previous month):

Reproducible builds

Whilst anyone can inspect the source code of free software for malicious flaws almost all software is distributed pre-compiled to end users.

The motivation behind the Reproducible Builds effort is to ensure no flaws have been introduced during this compilation process by promising identical results are always generated from a given source, thus allowing multiple third-parties to come to a consensus on whether a build was compromised.

This month I:

  • Performed a Non Maintainer Upload of the GNU mtools package in order to address two reproducibility-related bugs (#900409 & #900410) that are blocking the inclusion of my previous merge request to the Debian Installer to make the installation images (ISO, hd-media, netboot, etc,) bit-for-bit reproducible.
  • Kept isdebianreproducibleyet.com up to date. [...]
  • Submitted the following patches to fix reproducibility-related toolchain issues within Debian:
    • ogdi-dfsg: Please make the build (mostly) reproducible. (#903442)
    • schroot: Please make the documentation build reproducibly. (#902804)
  • I also submitted a patch to fix a specific reproducibility issue in v4l2loopback.
  • Worked on publishing our weekly reports. (#166, #167, #168, #169 & #170)
  • I also made the following changes to diffoscope, our in-depth and content-aware diff utility that can locate and diagnose reproducibility issues:
    • Support .deb archives that contain an uncompressed data tarball. (#903401)
    • Wrap jsondiff calls with a try-except to prevent errors becoming fatal. (#903447, #903449)
    • Clear the progress bar after completion. (#901758)
    • Support .deb archives that contain an uncompressed control tarball. (#903391)
  • Categorised a large number of packages and issues in the Reproducible Builds "notes" repository.

Debian LTS

This month I have worked 18 hours on Debian Long Term Support (LTS) and 11.75 hours on its sister Extended LTS project:

  • "Frontdesk" duties, triaging CVEs, responding to user questions/queries, etc.
  • Hopefully final updates to various scripts — both local and shared — to accommodate and support the introduction of the new "Extended LTS" initiative.
  • Issued DLA 1417-1 for ca-certificates, updating the set of Certificate Authority (CA) certificates that are considered "valid" or otherwise should be trusted by systems.
  • Issued DLA 1419-1 for ruby-sprockets to fix a path traversal issue exploitable via file:// URIs.
  • Issued DLA 1420-1 for the Cinnamon Desktop Environment where a symlink attack could permit an attacker to overwrite an arbitrary file on the filesystem.
  • Issued DLA 1427-1 for znc to address a path traversal vulnerability via ../ filenames in "skin" names as well as to fix an issue where insufficient validation could allow writing of arbitrary values to the znc.conf config file.
  • Issued DLA 1443-1 for evolution-data-server to fix an issue where rejected requests to upgrade to a secure connection did not result in the termination of the connection.
  • Issued DLA 1448-1 for policykit-1, uploading Abhijith PA's fix for a denial of service vulnerability.
  • Issued ELA-13-1 for ca-certificates, also updating the set of Certificate Authority (CA) certificates that are considered "valid" or otherwise should be trusted by wheezy systems.


Finally, I also sponsored elpy (1.22.0-1) & wolfssl (3.15.3+dfsg-1) and I orphaned dbus-cpp (#904426) and process-cpp (#904425) as they were no longer required as build-dependencies of Anbox.

Debian bugs filed

  • cod-tools: Missing build-depends. (#903689)
  • network-manager-openvpn: "Cannot specify device when activating VPN" error when connecting. (#903109)
  • ukwm: override_dh_auto_test doesn't respect nocheck build profile. (#904889)
  • ITP: gpg-encrypted-root — Encrypt root volumes with an OpenPGP smartcard. (#903163)
  • gnumeric: ssconvert segmentation faults. (#903194)
