This update for libmirage fixes the following issues :
CVE-2019-15540: The CSO filter in libMirage in CDemu did not validate the part size, triggering a heap-based buffer overflow that could lead to root access by a local user. [boo#1148087]
Update to new upstream release 3.2.2
ISO parser: fixed ISO9660/UDF pattern search for sector sizes 2332 and 2336.
ISO parser: added support for Nintendo GameCube and Wii ISO images.
Extended medium type guess to distinguish between DVD and BluRay images based on length.
Removed fabrication of disc structures from the library (moved to CDEmu daemon).
MDS parser: cleanup of disc structure parsing, fixed the incorrectly set structure sizes.
