Descriptions
In NTFS-3G versions < 2021.8.22, when specially crafted NTFS attributes are read in the function ntfs_attr_pread_i, a heap buffer overflow can occur and allow for writing to arbitrary memory or denial of service of the application.
En NTFS-3G versiones anteriores a 2021.8.22, cuando se leen atributos NTFS especialmente diseñados en la función ntfs_attr_pread_i, puede ocurrir un desbordamiento del búfer de la pila y permitir la escritura en memoria arbitraria o la denegación de servicio de la aplicación
The ntfs3g package is susceptible to a heap overflow on crafted input. When processing NTFS attributes, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
