PlayStation TIM loader computes CLUT size as
guint clut_size = num_colors * num_cluts;
Both operands are gushort. After integer promotion, 65535 * 65535 = 4,294,836,225 > INT_MAX → undefined behavior. UBSan-detected; plug-in aborts.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
