Description
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.

Weaknesses
CWE · root cause- CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
- CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
