function resulting in a denial of service or possibly code execution
(CVE-2018-12900)

* libtiff: Out-of-bounds write in tif_jbig.c (CVE-2018-18557)

* libtiff: NULL pointer dereference in tif_print.c:TIFFPrintDirectory()
causes a denial of service (CVE-2018-7456)

* libtiff: heap-based buffer overflow in tif_lzw.c:LZWDecodeCompat() allows
for denial of service (CVE-2018-8905)

* libtiff: heap-based buffer over-read in TIFFWriteScanline function in
tif_write.c (CVE-2018-10779)

* libtiff: reachable assertion in TIFFWriteDirectorySec function in
tif_dirwrite.c (CVE-2018-10963)

* libtiff: Integer overflow in multiply_ms in tools/ppm2tiff.c
(CVE-2018-17100)

* libtiff: Two out-of-bounds writes in cpTags in tools/tiff2bw.c and
tools/pal2rgb.c (CVE-2018-17101)
