The issue is related to a heap-based buffer overflow in the zlog library, specifically in the `zlog rule new()` function. This occurs because the size of `record name` is limited to `MAXLEN PATH(1024) + 1`, but `file path` can contain data up to `MAXLEN CFG LINE(MAXLEN PATH*4) + 1`, leading to a missing check when copying `record name` from `file path + 1`. This can cause a buffer overflow, allowing an attacker to potentially overwrite the `zlog record fn` `record func` function pointer, resulting in arbitrary code execution or remote code execution (RCE).
