Description
A flaw was found in Redis community. The cluster bus packet parser, responsible for handling PING, PONG, and MEET packets, fails to properly validate string-carrying extensions for null-termination. This oversight allows a remote attacker to craft a malicious packet, leading to an out-of-bounds read when the packet's payload is processed. Successful exploitation of this vulnerability could result in the disclosure of sensitive information or a remote denial of service (DoS).
