Descriptions

An integer underflow issue exists in ntfs-3g 2017.3.23. A local attacker could potentially exploit this by running /bin/ntfs-3g with specially crafted arguments from a specially crafted directory to cause a heap buffer overflow, resulting in a crash or the ability to execute arbitrary code. In installations where /bin/ntfs-3g is a setuid-root binary, this could lead to a local escalation of privileges.

Existe un problema de desbordamiento de enteros en ntfs-3g versión 2017.3.23. Un atacante local podría potencialmente aprovechar esto mediante la ejecución del archivo /bin/ntfs-3g con argumentos especialmente creados desde un directorio especialmente creado para causar un desbordamiento del búfer de la pila, lo que resulta en un bloqueo o la capacidad de ejecutar código arbitrario. En instalaciones donde /bin/ntfs-3g es un binario setuid-root, esto podría conllevar a una escalada local de privilegios.

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, information leakage, and null pointer vulnerabilities.
