ghostscript - several vulnerabilities

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.

For the stable distribution (lenny), these problems have been fixed in
version 8.62.dfsg.1-3.2lenny5

For the testing distribution (squeeze) and the unstable distribution (sid),
these problems have been fixed in version 8.71~dfsg2-4

We recommend that you upgrade your ghostscript package.
