Descriptions

ntfs_attr_find in the ntfs.ko filesystem driver in the Linux kernel 4.15.0 allows attackers to trigger a stack-based out-of-bounds write and cause a denial of service (kernel oops or panic) or possibly have unspecified other impact via a crafted ntfs filesystem.

ntfs_attr_find en el controlador en el sistema de archivos ntfs.ko en el kernel de Linux 4.15.0 permite que los atacantes desencadenen una escritura fuera de límites basada en la pila de memoria y provoquen una denegación de servicio (OOPS o pánico del kernel) o, posiblemente, provoquen otro impacto no especificado mediante un sistema de archivos ntfs manipulado.

A flaw was found in ntfs_attr_find in the ntfs.ko filesystem driver in the Linux kernel. This allows attackers to trigger a stack-based out-of-bounds write and cause a denial of service or possibly have unspecified other impact via a crafted ntfs filesystem image. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
