This is https://github.com/mm2/Little-CMS/issues/553, from upstream: "Fortunately, the memory being written lies in unallocated blocks, and there is no way for an attacker to control the overwritten contents, so it cannot be used as an exploit."

I'll downgrade this to low and wait for the next upstream release.

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