CVE-2021-32626: Specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. CVE-2021-32627: An integer overflow bug in Redis 5.0 or newer can be exploited to corrupt the heap and potentially result with remote code execution. CVE-2021-32628: An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. CVE-2021-32672: When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer. CVE-2021-32675: When parsing an incoming Redis Standard Protocol (RESP) request, Redis allocates memory according to user-specified values which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). CVE-2021-32687: An integer overflow bug affecting all versions of Redis can be exploited to corrupt the heap and potentially be used to leak arbitrary contents of the heap or trigger remote code execution. CVE-2021-32762: The redis-cli command line tool and redis-sentinel service may be vulnerable to integer overflow when parsing specially crafted large multi-bulk network replies. CVE-2021-41099: An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution.
