Description
In Redis community the cluster bus PING/PONG/MEET packet parser validated extension padding
and total length but never checked that string-carrying extensions are
properly null-terminated, allowing a crafted packet to trigger
out-of-bounds reads when the payload is later consumed as a C string. This vulnerability can potentially lead to loss of confidentiality or remote denial of service. Redis Software / Redis Enterprise are not affected by this issue.
