A Denial of Service (DoS) vulnerability exists in the jaraco/zipp library, affecting all versions prior to 3.19.1. The vulnerability is triggered when processing a specially crafted zip file that leads to an infinite loop. This issue also impacts the zipfile module of CPython, as features from the third-party zipp library are later merged into CPython, and the affected code is identical in both projects. The infinite loop can be initiated through the use of functions affecting the `Path` module in both zipp and zipfile, such as `joinpath`, the overloaded division operator, and `iterdir`. Although the infinite loop is not resource exhaustive, it prevents the application from responding. The vulnerability was addressed in version 3.19.1 of jaraco/zipp.
Existe una vulnerabilidad de denegación de servicio (DoS) en la librería jaraco/zipp que afecta a todas las versiones anteriores a la 3.19.1. La vulnerabilidad se activa al procesar un archivo zip especialmente manipulado que genera un bucle infinito. Este problema también afecta al módulo zipfile de CPython, ya que las funciones de la librería zipp de terceros se fusionan posteriormente en CPython y el código afectado es idéntico en ambos proyectos. El bucle infinito se puede iniciar mediante el uso de funciones que afectan al módulo `Path` tanto en zipp como en zipfile, como `joinpath`, el operador de división sobrecargado e `iterdir`. Aunque el bucle infinito no agota los recursos, impide que la aplicación responda. La vulnerabilidad se solucionó en la versión 3.19.1 de jaraco/zipp.
