Qt 6 through 6.6 was discovered to contain a NULL pointer dereference via the function QXcbConnection::initializeAllAtoms(). NOTE: this is disputed because it is not expected that an X application should continue to run when there is arbitrary anomalous behavior from the X server.
The product dereferences a pointer that it expects to be valid but is NULL.
