Multiple vulnerabilities in libtiff before 3.8.1 allow context-dependent attackers to cause a denial of service via a TIFF image that triggers errors in (1) the TIFFFetchAnyArray function in (a) tif_dirread.c; (2) certain "codec cleanup methods" in (b) tif_lzw.c, (c) tif_pixarlog.c, and (d) tif_zip.c; (3) and improper restoration of setfield and getfield methods in cleanup functions within (e) tif_jpeg.c, tif_pixarlog.c, (f) tif_fax3.c, and tif_zip.c.

Double free vulnerability in tif_jpeg.c in libtiff before 3.8.1 allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted TIFF image that triggers errors related to "setfield/getfield methods in cleanup functions."

Integer overflow in the TIFFFetchData function in tif_dirread.c for libtiff before 3.8.1 allows context-dependent attackers to cause a denial of service and possibly execute arbitrary code via a crafted TIFF image.

Stack-based buffer overflow in libTIFF before 3.7.2 allows remote attackers to execute arbitrary code via a TIFF file with a malformed BitsPerSample tag.

Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.

Integer overflow in (1) tif_dirread.c and (2) tif_fax3.c for libtiff 3.5.7 and 3.7.0 allows remote attackers to execute arbitrary code via a TIFF file containing a TIFF_ASCII or TIFF_UNDEFINED directory entry with a -1 entry count, which leads to a heap-based buffer overflow.

Integer overflow in the tiffdump utility for libtiff 3.7.1 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted TIFF file.

Multiple vulnerabilities in the RLE (run length encoding) decoders for libtiff 3.6.1 and earlier, related to buffer overflows and integer overflows, allow remote attackers to execute arbitrary code via TIFF files.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.
