Description
A malicious or compromised server can send a row containing fewer fields than
its row description declares columns. Reading one of the missing columns then
panics with an out-of-bounds index, aborting the calling task. This affects even
the otherwise non-panicking try_get, and both Row and SimpleQueryRow.
Applications that connect only to a trusted database are not exposed; the risk applies to clients that may connect to untrusted or user-supplied servers, or whose connection can be intercepted by a man-in-the-middle.
