"Two security issues have been discovered in Ghostscript, the GPL
PostScript/PDF interpreter. The Common Vulnerabilities and Exposures
project identifies the following problems :

  - CVE-2009-4897
    A buffer overflow was discovered that allows remote
    attackers to execute arbitrary code or cause a denial of
    service via a crafted PDF document containing a long
    name.

  - CVE-2010-1628
    Dan Rosenberg discovered that ghostscript incorrectly
    handled certain recursive Postscript files. An attacker
    could execute arbitrary code via a PostScript file
    containing unlimited recursive procedure invocations,
    which trigger memory corruption in the stack of the
    interpreter."
