Summary
Fix critical severity security issue in
tool/showwal.c.Vulnerability
V-001tool/showwal.c:184Description: Seven unbounded sprintf() calls in tool/showwal.c write formatted output into fixed-size stack buffers (zBuf, zDesc) without specifying a maximum output length. No validation is performed on WAL file field values before they are formatted. A crafted WAL file with oversized integer values or unexpected field contents can overflow these stack buffers, overwriting the saved return address and enabling arbitrary code execution.
