REDHAT-BUG-2513105: Redis redis vulnerability

An out-of-bounds read vulnerability in Redis through 8.8.1 allows an adjacent unauthenticated attacker to cause denial of service or information disclosure by sending a specially crafted PING message to the Redis Cluster Bus port. The getPingExtLength() function in the cluster bus message parser does not validate extension length fields against the actual remaining buffer size, allowing an attacker-controlled packet to cause the parser to read beyond the allocated buffer boundary.
