Use-after-free vulnerability in the t2p_readwrite_pdf_image function in tools/tiff2pdf.c in libtiff 4.0.3 allows remote attackers to cause a denial of service (crash) or possible execute arbitrary code via a crafted TIFF image.
The LZW decompressor in the gif2tiff tool in libtiff 4.0.3 and earlier allows context-dependent attackers to cause a denial of service (out-of-bounds write and crash) or possibly execute arbitrary code via a crafted GIF image.
Heap-based buffer overflow in the readgifimage function in the gif2tiff tool in libtiff 4.0.3 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted height and width values in a GIF image.
Multiple buffer overflows in libtiff before 4.0.3 allow remote attackers to cause a denial of service (out-of-bounds write) via a crafted (1) extension block in a GIF image or (2) GIF raster image to tools/gif2tiff.c or (3) a long filename for a TIFF image to tools/rgb2ycbcr.c. NOTE: vectors 1 and 3 are disputed by Red Hat, which states that the input cannot exceed the allocated buffer size.
