Changeset 8cb80fc92ece made by Panagiotis Koutsourakis kutsurak@monetdbsolutions.com in the MonetDB repo, refers to this bug.

For complete details, see http//devmonetdborg/hg/MonetDB?cmd=changeset;node=8cb80fc92ece

Changeset description:

Make sure we don't touch memory that doesn't belong to us

The list argument of the function readConfFileFull has been allocated
statically, and now has length of 64. The convention in the existing code is
that the last entry is a sentinel, so in total we can use 63 entries. Make sure
we don't write past the last entry.

This fixes bug #6318
