  apport (2.20.1-0ubuntu2.23) xenial-security; urgency=medium

  * SECURITY UPDATE: World writable root owned lock file created in user
    controllable location (LP: #1862348)
    - data/apport: Change location of lock file to be directly under
      /var/run so that regular users can not directly access it or perform
      symlink attacks.
    - CVE-2020-8831
  * SECURITY UPDATE: Race condition between report creation and ownership
    (LP: #1862933)
    - data/apport: When setting owner of report file use a file-descriptor
      to the report file instead of its path name to ensure that users can
      not cause Apport to change the ownership of other files via a
      symlink attack.

  apport (2.20.1-0ubuntu2.22) xenial-security; urgency=medium

  [ Michael Hudson-Doyle ]
  * SECURITY REGRESSION: fix autopkgtest failures since recent security
    update (LP: #1854237)
    - Fix regression in creating report for crashing setuid process by getting
      kernel to tell us the executable path rather than reading
      /proc/[pid]/exe.
    - Fix deletion of partially written core files.
    - Fix test_get_logind_session to use new API.
    - Restore add_proc_info raising ValueError for a dead process.
    - Delete test_lock_symlink, no longer applicable now that the lock is
      created in a directory only root can write to.

  [ Tiago Stürmer Daitx ]
  * SECURITY REGRESSION: 'module' object has no attribute 'O_PATH'
    (LP: #1851806)
    - apport/report.py, apport/ui.py: use file descriptors for /proc/pid
      directory access only when running under python 3; prevent reading /proc
      maps under python 2 as it does not provide a secure way to do so; use
      io.open for better compatibility between python 2 and 3.
  * data/apport: fix number of arguments passed through socks into a container.
  * test/test_report.py: test login session with both pid and proc_pid_fd.
  * test/test_apport_valgrind.py: skip test_sandbox_cache_options if system
    has little memory.
  * test/test_ui.py: modify run_crash_kernel test to account for the fact that
    linux-image-$kvers-$flavor is now built from the linux-signed source
    package on amd64 and ppc64el. (LP: #1766740)

  apport (2.20.1-0ubuntu2.21) xenial-security; urgency=medium

  * SECURITY REGRESSION: missing argument in Report.add_proc_environ
    call (LP: #1850929)
    - apport/report.py: call add_proc_environ using named arguments
      and move proc_pid_dir keyword to last to keep api compatibility.

      to Kevin Backhouse for the patch)
    - data/apport, apport/report.py, apport/ui.py: only access or open
      /proc/[pid] through a file descriptor for that directory.
