Descriptions
Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.
Múltiples desbordamientos de entero en las funciones (1) v9fs_xattr_read y (2) v9fs_xattr_write en hw/9pfs/9p.c en QEMU (también conocido como Quick Emulator) permiten a administradores locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) mediante un desplazamiento manipulado, lo que desencadena un acceso fuera de los límites.
