Description

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.
