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. This is a result of an incomplete fix by CVE-2021-29477. The
problem is fixed in version 6.2.4 and 6.0.14. 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. On
64 bit systems which have the fixes of CVE-2021-29477 (6.2.3 or 6.0.13), it
is sufficient to make sure that the proto-max-bulk-len config parameter is
smaller than 2GB (default is 512MB).
