The remote host is missing an update to ghostscript
announced via advisory USN-961-1.
Details follow:
David Srbecky discovered that Ghostscript incorrectly handled debug
logging. If a user or automated system were tricked into opening a crafted
PDF file, an attacker could cause a denial of service or execute arbitrary
code with privileges of the user invoking the program. This issue only
affected Ubuntu 9.04 and Ubuntu 9.10. The default compiler options for
affected releases should reduce the vulnerability to a denial of service.
(CVE-2009-4270)
