bridge: netfilter: fix information leak Struct tmp is copied from userspace. It is not checked whether the "name" field is NULL terminated. This may lead to buffer overflow and passing contents of kernel stack as a module name to try_then_request_module() and, consequently, to modprobe commandline. It would be seen by all userspace processes. Signed-off-by: Vasiliy Kulikov <segoon@openwall.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
