  script_tag(name:"insight", value:"Ghostscript is a set of software that provides a PostScript interpreter, a
  set of C procedures (the Ghostscript library, which implements the graphics
  capabilities in the PostScript language) and an interpreter for Portable
  Document Format (PDF) files.

  An integer overflow flaw was found in Ghostscript's TrueType bytecode
  interpreter. An attacker could create a specially-crafted PostScript or PDF
  file that, when interpreted, could cause Ghostscript to crash or,
  potentially, execute arbitrary code. (CVE-2009-3743)

  Ghostscript included the current working directory in its library search
  path by default. If a user ran Ghostscript without the '-P-'
  option in an attacker-controlled directory containing a specially-crafted
  PostScript library file, it could cause Ghostscript to execute arbitrary
  PostScript code. With this update, Ghostscript no longer searches the
  current working directory for library files by default. (CVE-2010-4820)

  Note: The fix for CVE-2010-4820 could possibly break existing
  configurations. To use the previous, vulnerable behavior, run Ghostscript
  with the '-P' option (to always search the current working directory
  first).

  A flaw was found in the way Ghostscript interpreted PostScript Type 1 and
  PostScript Type 2 font files. An attacker could create a specially-crafted
  PostScript Type 1 or PostScript Type 2 font file that, when interpreted,
  could cause Ghostscript to crash or, potentially, execute arbitrary code.
  (CVE-2010-4054)

  Users of Ghostscript are advised to upgrade to these updated packages,
  which contain backported patches to correct these issues.");
