Description Andrej Nemec 2016-12-08 10:31:53 UTC

Integer overflow in tools/bmp2tiff.c in LibTIFF before 4.0.4 allows
remote attackers to cause a denial of service (heap-based buffer
over-read), or possibly obtain sensitive information from process
memory, via crafted width and length values in RLE4 or RLE8 data in a
BMP file.
