H5O__pline_decode() Make more resilient to out-of-bounds read (#2210) (#2733)
Malformed hdf5 files may have trunkated content which does not match
the expected size. When this function attempts to decode these it may
read past the end of the allocated space leading to heap overflows
as bounds checking is incomplete.
Make sure each element is within bounds before reading.
This fixes CVE-2019-8396 / HDFFV-10712 / github bug #2209.
