Description Tomas Hoger 2010-06-03 10:26:15 EDT
iDefense reported to us a libtiff flaw discovered by Dan Rosenberg.  Quoting description from iDefense advisory draft:

  Remote exploitation of a stack buffer overflow vulnerability in
  version 3.9.2 of LibTIFF, as included in various vendors' operating
  system distributions, could allow an attacker to execute arbitrary
  code with the privileges of the current user.

  ...

  This vulnerability is due to insufficient bounds checking when copying
  data into a stack allocated buffer. During the processing of a certain
  EXIF tag a fixed sized stack buffer is used as a destination location
  for a memory copy. This memory copy can cause the bounds of a stack
  buffer to be overflown and this condition may lead to arbitrary code
  execution.
