Subject: Make sure info block for external links has at least 3 bytes
|
|
Patch-mainline: Not yet
|
|
Git-repo: ssh://eich@192.168.122.1:/home/eich/sources/HPC/hdf5

Git-commit: 082bfe392b04b1137da9eabd1ecac76c212ab385
|
|
References:
|
|
|
|
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 would be one
|
|
byte.
|
|
|
|
This fixes CVE-2018-16438.
