2017-03-13Fix boundary value negation in bmp_read_headerchromium/3041Nicolas Pena
When the value read is equal to -INT_MIN, we cannot negate it since it will be out of bounds, so return error in this case.

2017-03-07Limit BMP width to avoid overflowsNicolas Pena
BMP_WIDTHBYTES starts with: (width * bitCount) + 31. Since bitCount can be as large as 32, to avoid this overflowing we need width <= 67108863.

2016-11-28Replace ASSERT with error return in bmp_read_headernpm
The width and compress flag are read, so returning with error is more appropriate than having an ASSERT. BUG=659497 Review-Url: https://codereview.chromium.org/2535863002
