>Description:
devel/libytnef/ytnef.c has incomplete handling of the PT_CLSID type and will spin off and crash applications attempting to use it.

Patch attached properly handles the GUID data structure via hardcoded magic values.

Fix ideas were liberally stolen from the MSDN docs and wine.org handling code.
