Prior to version 0.1.11, RaTeX’s recursive-descent parser recurses one (or more) native stack frame per nesting level at `{`, `\\left`, `\\sqrt{`, `^{`, etc, with no maximum depth limit. A short, ~10 KB input of nested groups overflows the 8 MB main-thread stack and aborts the process. With `panic = \"abort\"` (`Cargo.toml:48`), and because a Rust stack overflow is always a fatal `SIGABRT` regardless of panic strategy this is an unrecoverable, whole-process denial of service reachable from a single untrusted LaTeX string. Version 0.1.11 fixes the issue."},{"lang":"es","value":"RaTeX es un motor de renderizado de matemáticas compatible con KaTeX escrito en Rust. Antes de la versión 0.1.11, el analizador descendente recursivo de RaTeX recurre a uno (o más) marcos de pila nativos por nivel de anidamiento en '{', '\\left', '\\sqrt{', '^{', etc., sin límite máximo de profundidad. Una entrada corta de ~10 KB de grupos anidados causa un desbordamiento de pila en la pila del hilo principal de 8 MB y aborta el proceso. Con 'panic = “abort”' ('Cargo.toml:48'), y debido a que un desbordamiento de pila de Rust es siempre un 'SIGABRT' fatal independientemente de la estrategia de pánico, esto es una denegación de servicio de proceso completo e irrecuperable alcanzable desde una única cadena LaTeX no confiable.
