Affected: crates.io: imageproc

A bounds check was performed in floating points before a cast to the index passed to an unchecked access function. This checked considered `NaN` cases improperly, causing them to succeed the check instead of failing it. The floating point coordinate is under caller control by passing a selected projection matrix.

Carefully controlling the coordinates of an image with no data and one non-zero dimension provides an arbitrary read primitive in the first 32-bits of address space with a Bilinear sampling method.

Using bicubic sampling can result in a read of a few bytes beyond an allocation.

Other out-of-bounds reads may be possible.
