cups CVE-2011-3170

the patch come from:
http://cups.org/strfiles/3914/str3914.patch

The gif_read_lzw function in filter/image-gif.c in CUPS 1.4.8 and
earlier does not properly handle the first code word in an LZW stream,
which allows remote attackers to trigger a heap-based buffer overflow,
and possibly execute arbitrary code, via a crafted stream, a different
vulnerability than CVE-2011-2896.
