Description:
 Redis is an open source (BSD licensed), in-memory data structure store,
 used as a database, cache, and message broker. An integer overflow bug in
 Redis version 6.0 or newer could be exploited using the `STRALGO LCS`
 command to corrupt the heap and potentially result with remote code
 execution. The problem is fixed in version 6.2.3 and 6.0.13. An additional
 workaround to mitigate the problem without patching the redis-server
 executable is to use ACL configuration to prevent clients from using the
 `STRALGO LCS` command.
