Large tuple features and Host field rewrites can flow through txn_box from request-controlled input. Several paths used alloca with sizes derived from those values, which could consume a large fraction of the ATS thread stack or overflow it outright. This bounds the temporary filter tuple array by a byte budget and aligns Host field rewrite buffers with the core host-name limit. Oversized filter input now returns an error, while oversized Host rewrites leave the existing Host field unchanged instead of allocating a large stack buffer. -- This is an automated message from the Apache Git Service.
