Name of the Vulnerable Software and Affected Versions LibRaw versions prior to 0.21.4

Description The issue is related to out-of-bounds reads in the phase one correct function within decoders/load mfbacks.cpp for tag 0x412 processing. This is caused by large w0 or w1 values or the frac and mult calculations.

Recommendations For versions prior to 0.21.4, update to version 0.21.4 or later to resolve the issue. As a temporary workaround, consider restricting the input values for w0 and w1 to prevent large values that could cause out-of-bounds reads.
