MFH: r369921

- Update to patchlevel 4.3.29.

  This addresses the local crash from CVE-2014-6277. Note that
  the fixes applied in 4.3.25_2 (and upstream 4.3.27) already made
  this non-exploitable remotely.

  This makes 'bashcheck' [1] fully green now. It had a soft warning
  before for CVE-2014-6277.
