Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of file name extensions. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root.

No es requerida autenticaci\u00f3n para explotar esta vulnerabilidad. El fallo espec\u00edfico se presenta en el an\u00e1lisis de las extensiones de los nombres de los archivos. El problema es debido a que no es comprobada apropiadamente la longitud de los datos suministrados por el usuario antes de copiarlos en un b\u00fafer de longitud fija en la regi\u00f3n stack de la memoria.
