CVE-2022-35951: Redis subject to Integer Overflow leading to Remote Code Execution via Heap Overflow
Redis is an in-memory database that persists on disk. Versions 7.0.0 and above, prior to 7.0.5 are vulnerable to an Integer Overflow. Executing an XAUTOCLAIM command on a stream key in a specific state, with a specially crafted COUNT argument may cause an integer overflow, a subsequent heap overflow, and potentially lead to remote code execution. This has been patched in Redis version 7.0.5. No known workarounds exist.
