Package : cups
Date : October 11, 2011
Affected: 2009.0, 2010.1, Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
Multiple vulnerabilities has been discovered and corrected in cups:
The cupsDoAuthentication function in auth.c in the client in CUPS
before 1.4.4, when HAVE_GSSAPI is omitted, does not properly handle a
demand for authorization, which allows remote CUPS servers to cause
a denial of service (infinite loop) via HTTP_UNAUTHORIZED responses
(CVE-2010-2432).
The LZW decompressor in the LWZReadByte function in giftoppm.c in
the David Koblas GIF decoder in PBMPLUS, as used in the gif_read_lzw
function in filter/image-gif.c in CUPS before 1.4.7, the LZWReadByte
function in plug-ins/common/file-gif-load.c in GIMP 2.6.11 and earlier,
the LZWReadByte function in img/gifread.c in XPCE in SWI-Prolog 5.10.4
and earlier, and other products, does not properly handle code words
that are absent from the decompression table when encountered, which
allows remote attackers to trigger an infinite loop or a heap-based
buffer overflow, and possibly execute arbitrary code, via a crafted
compressed stream, a related issue to CVE-2006-1168 and CVE-2011-2895
(CVE-2011-2896).
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 (CVE-2011-3170).
Packages for 2009.0 are provided as of the Extended Maintenance
Program. Please visit this link to learn more:
