[Libpst-devel] _pst_read_block_size errors

[Nigel Horne]

In _pst_read_block_size if the number of bytes read is small (typically 0)
the software reads uninitialised values because it does things such as
read buf[0], even though no data has been read into it.

Here's the proposed fix:

        DEBUG_WARN(("I can't tell why it failed\n"));
      }
+ 	if(rsize <= 2) {
+ 		fseek(pf->fp, fpos, SEEK_SET);
+ 		*buf = '\0';
+ 		return 0;
+ 	}
      size = rsize;
    }
