The vulnerability occurs in the SubWordJapaneseTokenizer class, where regular expressions process specially crafted inputs. The issue stems from a regex exhibiting exponential complexity under certain conditions, leading to excessive backtracking. This can result in high CPU usage and potential application downtime, effectively creating a Denial of Service (DoS) scenario. The affected version is v4.48.1 (latest)."},{"lang":"es","value":"Se identificó una vulnerabilidad de denegación de servicio por expresión regular (ReDoS) en la librería huggingface/transformers, concretamente en el archivo `tokenization_gpt_neox_japanese.py` del modelo GPT-NeoX-Japanese. La vulnerabilidad se produce en la clase SubWordJapaneseTokenizer, donde las expresiones regulares procesan entradas especialmente manipuladas. El problema se debe a que una expresión regular presenta una complejidad exponencial en determinadas condiciones, lo que provoca un retroceso excesivo. Esto puede provocar un alto consumo de CPU y un posible tiempo de inactividad de la aplicación, creando así un escenario de denegación de servicio (DoS).
