CVE-2016-4333

Published: 18 November 2016

The HDF5 1.8.16 library allocating space for the array using a value from the file has an impact within the loop for initializing said array allowing a value within the file to modify the loop's terminator. Due to this, an aggressor can cause the loop's index to point outside the bounds of the array when initializing it.

From the Ubuntu Security Team

It was discovered that HDF5 incorrectly handled memory allocation. An attacker could possibly use this issue to execute arbitrary code.
