CVE-2011-2896

Status Candidate

Overview

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.

Red Hat Security Advisory 2012-1180-01 - The GIMP is an image composition and editing program. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the GIMP's GIF image format plug-in. An attacker could create a specially-crafted GIF image file that, when opened, could cause the GIF plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP. A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch decompression algorithm implementation used by the GIMP's GIF image format plug-in. An attacker could create a specially-crafted GIF image file that, when opened, could cause the GIF plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP.

Red Hat Security Advisory 2012-0302-03 - The Common UNIX Printing System provides a portable printing layer for Linux, UNIX, and similar operating systems. A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch decompression algorithm implementation used by the CUPS GIF image format reader. An attacker could create a malicious GIF image file that, when printed, could possibly cause CUPS to crash or, potentially, execute arbitrary code with the privileges of the "lp" user.

Mandriva Linux Security Advisory 2011-167 - A vulnerability has been discovered and corrected in gimp. 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. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory 2011-146 - 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 via HTTP_UNAUTHORIZED responses. 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 and CVE-2011-2895. 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.
