CVE-2021-39257

Una imagen NTFS diseñada con un mapa de bits sin asignar puede conllevar a una cadena interminable de llamadas a funciones recursivas (empezando por ntfs_attr_pwrite), causando un consumo de la pila en NTFS-3G versiones anteriores a 2021.8.22

The ntfs3g package is susceptible to a heap overflow on crafted input. When processing an NTFS image, proper bounds checking was not enforced leading to this software flaw. The highest threat from this vulnerability is system availability.

Kernel-based Virtual Machine offers a full virtualization solution for Linux on numerous hardware platforms. The virt:rhel module contains packages which provide user-space components used to run virtual machines using KVM. The packages also provide APIs for managing and interacting with the virtualized systems. Issues addressed include buffer overflow, integer overflow, null pointer, out of bounds access, out of bounds read, and use-after-free vulnerabilities.
