Descriptions

kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor states "there is no kernel bug here.

** DISPUTADA ** kernel/ptrace.c en el kernel de Linux hasta la versión 4.4.1 no maneja correctamente el mapeo uid y gid, lo que permite a usuarios locales obtener privilegios estableciendo un espacio de nombres de usuario, a la espera de un proceso root para entrar ese espacio de nombres con un uid o gid inseguro, y después utilizando la llamada al sistema ptrace. NOTA: el vendedor afirma "no hay ningún error en el kernel aquí".
