Summary
A Regular Expression Denial of Service (ReDoS) vulnerability was identified in the huggingface/transformers library, specifically in the file `tokenization_gpt_neox_japanese.py` of the GPT-NeoX-Japanese model. 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).

      "value": "Se identific\u00f3 una vulnerabilidad de denegaci\u00f3n de servicio por expresi\u00f3n regular (ReDoS) en la librer\u00eda 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 expresi\u00f3n 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 aplicaci\u00f3n, creando as\u00ed un escenario de denegaci\u00f3n de servicio (DoS). La versi\u00f3n afectada es la v4.48.1 (\u00faltima versi\u00f3n)."
