    Summary: Stack overflow during recursive expression parsing

    Details: When parsing untrusted rulex expressions, the stack may overflow, possibly enabling a Denial of Service attack. This happens when parsing an expression with several hundred levels of nesting, causing the process to abort immediately. The flaw was corrected in commits `60aa2dc03a` by adding a check to recursion depth.
