Jan Kara eee3ed05f6 udf: Check component length before reading it 
commit e237ec37ec upstream.

Check that length specified in a component of a symlink fits in the
input buffer we are reading. Also properly ignore component length for
component types that do not use it. Otherwise we read memory after end
of buffer for corrupted udf image.
