In sam2p 0.49.3, there is an invalid read of size 2 in the parsergb function in inxpm.cpp. However, this can also cause a write to an illegal address.

Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element.

In sam2p 0.49.3, the pcxLoadRaster function in inpcx.cpp has an integer signedness error leading to a heap-based buffer overflow.

In sam2p 0.49.3, the inxpmreader function in inxpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element.
