redis v7.0.10 was discovered to contain a segmentation violation. This vulnerability allows attackers to cause a Denial of Service (DoS) via unspecified vectors.

Redis v7.0 was discovered to contain a memory leak via the component streamGetEdgeID.

Redis is an in-memory database that persists on disk. Prior to versions 6.2.7 and 7.0.0, 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. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to `SCRIPT LOAD` and `EVAL` commands using ACL rules.

Redis is an in-memory database that persists on disk. By exploiting weaknesses in the Lua script execution environment, an attacker with access to Redis prior to version 7.0.0 or 6.2.7 can inject Lua code that will execute with the (potentially higher) privileges of another Redis user. The Lua script execution environment in Redis provides some measures that prevent a script from creating side effects that persist and can affect the execution of the same, or different script, at a later time. Several weaknesses of these measures have been publicly known for a long time, but they had no security impact as the Redis security model did not endorse the concept of users or privileges. With the introduction of ACLs in Redis 6.0, these weaknesses can be exploited by a less privileged users to inject Lua code that will execute at a later time, when a privileged user executes a Lua script. The problem is fixed in Redis versions 7.0.0 and 6.2.7. An additional workaround to mitigate this problem…

Integer overflow in the getnum function in lua_struct.c in Redis 2.8.x before 2.8.24 and 3.0.x before 3.0.6 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow.
