Hi all,

We've just released Redis 6.2.7. This patch-level release addresses several issues, including fixes to two security vulnerabilities.

Following are the release notes:

Security Fixes

(CVE-2022-24736) An attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. This issue affects all versions of Redis.
[reported by Aviv Yahav].
(CVE-2022-24735) By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis can inject Lua code that will execute with the (potentially higher) privileges of another Redis user.
[reported by Aviv Yahav].
