Impact
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.
Patches
The problem is fixed in version 6.2.3 and 6.0.13.
Workarounds
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.
