CVE-2021-29477

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.
