Several issues were found in Ghostscript, the GPL PostScript/PDF
interpreter, which allow remote attackers to cause a denial of service
(heap-based buffer overflow and application crash) or possibly have
unspecified other impact via a crafted PostScript document.

For Debian 7 "Wheezy", these problems have been fixed in version
9.05~dfsg-6.3+deb7u7.

We recommend that you upgrade your ghostscript packages.
