Redis - 6.2.7


Upgrade urgency: SECURITY, contains fixes to security issues.

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].
