libtiff: Out-of-bounds reads followed by a crash in bmp2tiff

A flaw was discovered in the bmp2tiff utility. By tricking a user into processing a specially crafted file, a remote attacker could exploit this flaw to cause a crash or memory corruption and, possibly, execute arbitrary code with the privileges of the user running the libtiff tool...

libtiff: divide by zero in the tiffdither tool

The TIFFmalloc function in tifunix.c in LibTIFF 4.0.3 does not reject a zero size, which allows remote attackers to cause a denial of service divide-by-zero error and application crash via a crafted TIFF image that is mishandled by the TIFFWriteScanline function in tifwrite.c, as demonstrated by...

libtiff: out-of-bounds read with malformed TIFF image in multiple tools

LibTIFF 4.0.3 allows remote attackers to cause a denial of service out-of-bounds read and crash via a crafted TIFF image to the 1 checkInkNamesString function in tifdir.c in the thumbnail tool, 2 compresscontig function in tiff2bw.c in the tiff2bw tool, 3 putcontig8bitCIELab function in...

libtiff: out-of-bounds write in horizontalDifference8()

Heap-based buffer overflow in the horizontalDifference8 function in tifpixarlog.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...

libtiff: Out-of-bounds write in PixarLogDecode() function in tif_pixarlog.c

The TIFFVGetField function in tifdir.c in libtiff 4.0.6 allows attackers to cause a denial of service invalid memory write and crash or possibly have unspecified other impact via crafted field data in an extension tag in a TIFF image...

libtiff: Out-of-bounds reads followed by a crash in bmp2tiff

A flaw was discovered in the bmp2tiff utility. By tricking a user into processing a specially crafted file, a remote attacker could exploit this flaw to cause a crash or memory corruption and, possibly, execute arbitrary code with the privileges of the user running the libtiff tool...

libtiff: out-of-bound write in NeXTDecode()

The NeXTDecode function in tifnext.c in LibTIFF allows remote attackers to cause a denial of service out-of-bounds write via a crafted TIFF image, as demonstrated by libtiff5.tif...

libtiff: invalid assertion

tifluv.c in libtiff allows attackers to cause a denial of service out-of-bounds writes via a crafted TIFF image, a different vulnerability than CVE-2015-8781...

libtiff: out-of-bounds read/write with malformed TIFF image in tiff2pdf

LibTIFF 4.0.3 allows remote attackers to cause a denial of service out-of-bounds write or possibly have unspecified other impact via a crafted TIFF image, as demonstrated by failure of tifnext.c to verify that the BitsPerSample value is 2, and the t2psamplelabsignedtounsigned function in tiff2pdf...
