Descriptions

Integer overflow in the ISO9660 writer in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors related to verifying filename lengths when writing an ISO9660 archive, which trigger a buffer overflow.

Desbordamiento de entero en el escritor ISO9660 en libarchive en versiones anteriores a 3.2.1 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) o ejecutar código arbitrario a través de vectores relacionados con la verificación de longitudes de nombre de archivo cuando se escribe un archivo ISO9660, lo que desencadena un desbordamiento de búfer.

A vulnerability was found in libarchive. An attempt to create an ISO9660 volume with 2GB or 4GB filenames could cause the application to crash.
