GHSA-H762-RHV3-H25V OpenEXR: integer overflow to OOB write in uncompress_b44_impl()

Summary The B44/B44A decoder in OpenEXR reconstructs row pointers into a scratch buffer using int. When the channel width nx is large enough, the product y nx overflows int, causing the row pointer to wrap before the start of the scratch buffer. Subsequent memcpy calls then write decoded pixel...
