Details

Reginaldo Silva discovered that due to a packaging issue, a remote attacker
with the ability to execute arbitrary Lua scripts could possibly escape the
Lua sandbox and execute arbitrary code on the host.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 21.10

• redis-server - 5:6.0.15-1ubuntu0.1
