  "details": "tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to\ncause a denial of service (TIFFSetupStrips heap-based buffer overflow and\napplication crash) or possibly have unspecified other impact via a crafted\nTIFF file. (CVE-2017-17095)\n\nIn LibTIFF 4.0.8, there is a heap-based buffer overflow in the t2p_write_pdf\nfunction in tools/tiff2pdf.c. This heap overflow could lead to different\ndamages. For example, a crafted TIFF document can lead to an out-of-bounds\nread in TIFFCleanup, an invalid free in TIFFClose or t2p_free, memory\ncorruption in t2p_readwrite_pdf_image, or a double free in t2p_free. Given\nthese possibilities, it probably could cause arbitrary code execution.\n(CVE-2017-9935)\n\nIn LibTIFF 4.0.9, there is a Null-Pointer Dereference in the tif_print.c\nTIFFPrintDirectory function, as demonstrated by a tiffinfo crash.\n(CVE-2017-18013)\n",
