Free software activities in April 2017

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

Reproducible builds


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

The motivation behind the Reproducible Builds effort is to permit verification that no flaws have been introduced — either maliciously or accidentally — 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.

I have generously been awarded a grant from the Core Infrastructure Initiative to fund my work in this area.

This month I:

I also made the following changes to diffoscope, our recursive and content-aware diff utility used to locate and diagnose reproducibility issues:

  • New features:
    • Add support for comparing Ogg Vorbis files. (0436f9b)
  • Bug fixes:
    • Prevent a traceback when using --new-file with containers. (#861286)
    • Don't crash on invalid archives; print a useful error instead. (#833697).
    • Don't print error output from bzip2 call. (21180c4)
  • Cleanups:
    • Prevent abstraction-level violations by defining visual diff support on Presenter classes. (7b68309)
    • Show Debian packages installed in test output. (c86a9e1)


Debian

Debian LTS


This month I have been paid to work 18 hours on Debian Long Term Support (LTS). In that time I did the following:

  • "Frontdesk" duties, triaging CVEs, etc.
  • Issued DLA 882-1 for the tryton-server general application platform to fix a path suffix injection attack.
  • Issued DLA 883-1 for curl preventing a buffer read overrun vulnerability.
  • Issued DLA 884-1 for collectd (a statistics collection daemon) to close a potential infinite loop vulnerability.
  • Issued DLA 885-1 for the python-django web development framework patching two open redirect & XSS attack issues.
  • Issued DLA 890-1 for ming, a library to create Flash files, closing multiple heap-based buffer overflows.
  • Issued DLA 892-1 and DLA 891-1 for the libnl3/libnl Netlink protocol libraries, fixing integer overflow issues which could have allowed arbitrary code execution.
