CVE-2014-9645

The add_probe function in modutils/modprobe.c in BusyBox before 1.23.0 allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an "ifconfig /usbserial up" command or a "mount -t /snd_pcm none /" command.

Updated busybox packages fix security vulnerability:

The modprobe command in busybox before 1.23.0 uses the basename of the module argument as the module to load, allowing arbitrary modules, even when some kernel subsystems try to prevent this (CVE-2014-9645).

These are all security issues fixed in the busybox-1.35.0-6.1 package on the GA media of openSUSE Tumbleweed.
