Heap-based buffer overflow in the thunder (aka ThunderScan) decoder in tif_thunder.c in LibTIFF 3.9.4 and earlier allows remote attackers to execute arbitrary code via crafted THUNDER_2BITDELTAS data in a .tiff file that has an unexpected BitsPerSample value.
The TIFFExtractData macro in LibTIFF before 3.9.4 does not properly handle unknown tag types in TIFF directory entries, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted TIFF file.
LibTIFF 3.9.4 and earlier does not properly handle an invalid td_stripbytecount field, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted TIFF file, a different vulnerability than CVE-2010-2443.
The OJPEGReadBufferFill function in tif_ojpeg.c in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an OJPEG image with undefined strip offsets, related to the TIFFVGetField function.
Integer overflow in the TIFFroundup macro in LibTIFF before 3.9.3 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted TIFF file that triggers a buffer overflow.
Stack-based buffer overflow in the TIFFFetchSubjectDistance function in tif_dirread.c in LibTIFF before 3.9.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long EXIF SubjectDistance field in a TIFF file.
Multiple integer overflows in inter-color spaces conversion tools in libtiff 3.8 through 3.8.2, 3.9, and 4.0 allow context-dependent attackers to execute arbitrary code via a TIFF image with large (1) width and (2) height values, which triggers a heap-based buffer overflow in the (a) cvt_whole_image function in tiff2rgba and (b) tiffcvt function in rgb2ycbcr.
