block/cloop: refuse images with bogus offsets (CVE-2014-0144)
The offsets[] array allows efficient seeking and tells us the maximum
compressed data size. If the offsets are bogus the maximum compressed
data size will be unrealistic.
This could cause g_malloc() to abort and bogus offsets mean the image is
broken anyway. Therefore we should refuse such images.
