Make sure info block for external links has at least 3 bytes (#2234)
According to the specification, the information block for external links
contains 1 byte of version/flag information and two 0 terminated strings
for the object linked to and the full path.
Although not very useful, the minimum string length for each (with
terminating 0) would be one byte.
Checking this will help to avoid SEGVs triggered by bogus files.
This fixes CVE-2018-16438 / Bug #2233.
