Add upstream post-4.0.7 commits (except for ChangeLog modifications) fixing the following security issues: CVE-2016-10266 - LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_read.c:351:22. CVE-2016-10267 - LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted TIFF image, related to libtiff/tif_ojpeg.c:816:8. CVE-2016-10269 - LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 512" and libtiff/tif_unix.c:340:2. CVE-2016-10270 - LibTIFF 4.0.7 allows remote attackers to cause a denial of service (heap-based buffer over-read) or possibly have unspecified other impact via a crafted TIFF image, related to "READ of size 8" and libtiff/tif_read.c:523:22. CVE-2017-5225 - LibTIFF version 4.0.7 is vulnerable to a heap buffer overflow in the tools/tiffcp resulting in DoS or code execution via a crafted BitsPerSample value. CVE-2017-7592 - The putagreytile function in tif_getimage.c in LibTIFF 4.0.7 has a left-shift undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. CVE-2017-7593 - tif_read.c in LibTIFF 4.0.7 does not ensure that tif_rawdata is properly initialized, which might allow remote attackers to obtain sensitive information from process memory via a crafted image. CVE-2017-7594 - The OJPEGReadHeaderInfoSecTablesDcTable function in tif_ojpeg.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (memory leak) via a crafted image. CVE-2017-7595 - The JPEGSetupEncode function in tiff_jpeg.c in LibTIFF 4.0.7 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image. CVE-2017-7598 - tif_dirread.c in LibTIFF 4.0.7 might allow remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted image. CVE-2017-7601 - LibTIFF 4.0.7 has a "shift exponent too large for 64-bit type long" undefined behavior issue, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image. CVE-2017-7602 - LibTIFF 4.0.7 has a signed integer overflow, which might allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted image.
