The wordexp function in the GNU C Library (aka glibc) through 2.33 may crash or read arbitrary memory in parse_param (in posix/wordexp.c) when called with an untrusted, crafted pattern, potentially resulting in a denial of service or disclosure of information. This occurs because atoi was used but strtoul should have been used to ensure correct calculations.
La función wordexp de la biblioteca GNU C (también se conoce como glibc) versiones hasta 2.33, puede bloquearse o leer memoria arbitraria en la función parse_param (en el archivo posix/wordexp.c) cuando se llama con un patrón diseñado que no es confiable, resultando en una denegación de servicio o divulgación de información. Esto ocurre porque atoi fue usado pero debería haber sido usado strtoul para asegurar cálculos correctos
