[ubuntu/precise-updates] apport 2.0.1-0ubuntu17.10 (Accepted)

[Ubuntu Archive Robot]

apport (2.0.1-0ubuntu17.10) precise-security; urgency=medium

  * SECURITY FIX: kernel_crashdump: Enforce that the log/dmesg files are not a
    symlink.
    This prevents normal users from pre-creating a symlink to the predictable
    .crash file, and thus triggering a "fill up disk" DoS attack when the
    .crash report tries to include itself. Thanks to halfdog for discovering
    this! (CVE-2015-1338, part of LP #1492570)
  * SECURITY FIX: Fix all writers of report files to open the report file
    exclusively.
    Fix package_hook, kernel_crashdump, and similar hooks to fail if the
    report already exists. This prevents privilege escalation through symlink
    attacks. Note that this will also prevent overwriting previous reports
    with the same same. Thanks to halfdog for discovering this!
    (CVE-2015-1338, LP: #1492570)
  * debian/tests/upstream-system: Change directory to /tmp, so that tests
    actually run against the installed package.
