Bugs Fixed

A number of potential buffer overflow issues were found and fixed in the NDB codebase. (Bug #25260091)
References: See also: Bug #23152979.
ndb_restore did not restore tables having more than 341 columns correctly. This was due to the fact that the buffer used to hold table metadata read from .ctl files was of insufficient size, so that only part of the table descriptor could be read from it in such cases. This issue is fixed by increasing the size of the buffer used by ndb_restore for file reads. (Bug #25182956)
