SynopsisThe remote Debian host is missing a security update.
DescriptionNumerous security vulnerabilities have been found through fuzzing on various tiff-related binaries. Crafted TIFF images allows remote attacks to cause denial of service or, in certain cases arbitrary code execution through divide-by-zero, out of bunds write, integer and heap overflow.
The fpAcc function in tif_predict.c in the tiff2rgba tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero error) via a crafted TIFF image.
The rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (divide-by-zero) by setting the (1) v or (2) h parameter to 0. (Fixed along with CVE-2016-3624.)
The cvtClump function in the rgb2ycbcr tool in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds write) by setting the '-v' option to -1.
Multiple integer overflows in the (1) cvt_by_strip and (2) cvt_by_tile functions in the tiff2rgba tool in LibTIFF 4.0.6 and earlier, when -b mode is enabled, allow remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image, which triggers an out-of-bounds write.
Heap-based buffer overflow in the horizontalDifference8 function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image to tiffcp.
tif_pixarlog.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers. Reported as MSVR 35094, aka 'PixarLog horizontalDifference heap-buffer-overflow.'
tif_write.c in libtiff 4.0.6 has an issue in the error code path of TIFFFlushData1() that didn't reset the tif_rawcc and tif_rawcp members. Reported as MSVR 35095, aka 'TIFFFlushData1 heap-buffer-overflow.'
tif_predict.h and tif_predict.c in libtiff 4.0.6 have assertions that can lead to assertion failures in debug mode, or buffer overflows in release mode, when dealing with unusual tile size like YCbCr with subsampling. Reported as MSVR 35105, aka 'Predictor heap-buffer-overflow.'
tools/tiff2pdf.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in heap allocated buffers in t2p_process_jpeg_strip().
Reported as MSVR 35098, aka 't2p_process_jpeg_strip heap-buffer-overflow.'
tools/tiffcrop.c in libtiff 4.0.6 has out-of-bounds write vulnerabilities in buffers. Reported as MSVR 35093, MSVR 35096, and MSVR 35097.
tools/tiffcrop.c in libtiff 4.0.6 reads an undefined buffer in readContigStripsIntoBuffer() because of a uint16 integer overflow.
Reported as MSVR 35100.
tools/tiffcp.c in libtiff 4.0.6 has an out-of-bounds write on tiled images with odd tile width versus image width. Reported as MSVR 35103, aka cpStripToTile heap-buffer-overflow.
heap-buffer-overflow in tiffcrop
CVE-2016-10093 uint32 underflow/overflow that can cause heap-based buffer overflow in tiffcp
LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value.
heap-based buffer verflow in TIFFFillStrip (tif_read.c)
For Debian 7 'Wheezy', these problems have been fixed in version 4.0.2-6+deb7u9.
We recommend that you upgrade your tiff packages.
