• Miscellaneous memory safety hazards (rv:4.0) Mozilla
  identified and fixed several memory safety bugs in the
  browser engine used in SeaMonkey 2.2 and other
  Mozilla-based products. Some of these bugs showed
  evidence of memory corruption under certain
  circumstances, and we presume that with enough effort at
  least some of these could be exploited to run arbitrary
  code.
