This seems to be a CWE-372 ("Incomplete Internal State Distinction")
issue in which the code expected to be in a state where it was
operating on a set of validated URIs from a CALLBACK header, but
actually was in a state where it was operating on a set of all URIs
from a CALLBACK header. A validation step occurs for every URI, and
the amount of memory allocated is correct for the set of validated
URIs, but there is simply no data model for the set of validated URIs.
(Conceivably, the set of validated URIs could be in its own array, or
each URI in the original array could have a flag indicating whether it
was valid.)

Use CVE-2016-8863.

As mentioned, this has a resultant heap buffer overflow.
