  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, leading to a heap-based buffer overflow, was
  found in Ghostscript's International Color Consortium Format library
  (icclib). An attacker could create a specially-crafted PostScript or PDF
  file with embedded images that would cause Ghostscript to crash or,
  potentially, execute arbitrary code with the privileges of the user running
  Ghostscript. (CVE-2012-4405)

  Red Hat would like to thank Marc Schoenefeld for reporting this issue.

  Users of Ghostscript are advised to upgrade to these updated packages,
  which contain a backported patch to correct this issue.");
