Prior to versions 8.0.3, 5.2.2, 4.0.4, and 3.5.1, attempting to parse a patch whose filename headers contain the line break characters `\\r`, `\\u2028`, or `\\u2029` can cause the `parsePatch` method to enter an infinite loop. It then consumes memory without limit until the process crashes due to running out of memory. Applications are therefore likely to be vulnerable to a denial-of-service attack if they call `parsePatch` with a user-provided patch as input. A large payload is not needed to trigger the vulnerability, so size limits on user input do not provide any protection. Furthermore, some applications may be vulnerable even when calling `parsePatch` on a patch generated by the application itself if the user is nonetheless able to control the filename headers (e.g. by directly providing the filenames of the files to be diffed). The `applyPatch` method is similarly affected if (and only if) called with a string representation of a patch as an argument, since under the hood it parses that string using `parsePatch`. Other methods of the library are unaffected. Finally, a second and lesser interdependent bug - a ReDOS - also exhibits when those same line break characters are present in a patch's *patch* header (also known as its \"leading garbage\"). A maliciously-crafted patch header of length *n* can take `parsePatch` O(*n*³) time to parse. Versions 8.0.3, 5.2.2, 4.0.4, and 3.5.1 contain a fix. As a workaround, do not attempt to parse patches that contain any of these characters: `\\r`, `\\u2028`, or `\\u2029`."},{"lang":"es","value":"jsdiff es una implementación de diferenciación de texto en JavaScript. Antes de las versiones 8.0.3, 5.2.2, 4.0.4 y 3.5.1, intentar analizar un parche cuyos encabezados de nombre de archivo contienen los caracteres de salto de línea `\\r`, `\\u2028` o `\\u2029` puede hacer que el método `parsePatch` entre en un bucle infinito. Luego consume memoria sin límite hasta que el proceso falla por falta de memoria. Por lo tanto, las aplicaciones son propensas a ser vulnerables a un ataque de denegación de servicio si llaman a `parsePatch` con un parche proporcionado por el usuario como entrada. No se necesita una carga útil grande para activar la vulnerabilidad, por lo que los límites de tamaño en la entrada del usuario no proporcionan ninguna protección. Además, algunas aplicaciones pueden ser vulnerables incluso al llamar a `parsePatch` en un parche generado por la propia aplicación si el usuario, no obstante, puede controlar los encabezados de nombre de archivo (por ejemplo, proporcionando directamente los nombres de archivo de los archivos a diferenciar). El método `applyPatch` se ve afectado de manera similar si (y solo si) se llama con una representación de cadena de un parche como argumento, ya que internamente analiza esa cadena usando `parsePatch`. Otros métodos de la librería no se ven afectados. Finalmente, un segundo error menos interdependiente - un ReDOS - también se manifiesta cuando esos mismos caracteres de salto de línea están presentes en el encabezado *patch* de un parche (también conocido como su 'leading garbage'). Un encabezado de parche maliciosamente elaborado de longitud *n* puede tomarle a `parsePatch` un tiempo de O(*n*³) para analizar. Las versiones 8.0.3, 5.2.2, 4.0.4 y 3.5.1 contienen una corrección.
