Alpine: multiple redis packages: security update to 6.2.7-r0
high Tenable Cloud Security Plugin ID 406918
Description
There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:- 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 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. (CVE-2022-24735)
- 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.
