CVE-2023-25155: Integer Overflow in several Redis commands can lead to denial of service.

First published: Thu Mar 02 2023(Updated: )

Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted `SRANDMEMBER`, `ZRANDMEMBER`, and `HRANDFIELD` commands can trigger an integer overflow, resulting in a runtime assertion and termination of the Redis server process. This problem affects all Redis versions. Patches were released in Redis version(s) 6.0.18, 6.2.11 and 7.0.9.
