From 0d3ccf4cc54d3844bc9d1c8f6bdcd36180752a2c Mon Sep 17 00:00:00 2001 From: Jakub Zelenka Date: Tue, 8 Oct 2024 16:17:53 +0100 Subject: [PATCH 1/6] Fix GHSA-h35g-vwh6-m678: Mysqlnd - various heap buffer over-reads This fixes issues causing buffer over-read that leak heap content: - RESP packet field default left over for COM_LIST - RESP packet upsert filename - OK packet message - RESP packet for stmt row data - ps_fetch_from_1_to_8_bytes - ps_fetch_float - ps_fetch_double - ps_fetch_time - ps_fetch_date - ps_fetch_datetime - ps_fetch_string - ps_fetch_bit - RESP packet for query row data (just possible overflow on 32bit) It also adds various protocol tests using a new fake server.
