Описание
Оригинално описание
Dragonfly through 2.0.2 contains an unbounded memory allocation vulnerability that allows unauthenticated clients to exhaust memory by passing a negative COUNT to HRANDFIELD, ZRANDMEMBER or SRANDMEMBER. Attackers can send a single command against a one-element key with a huge negative COUNT to trigger the OOM killer, terminating the instance for all clients.
