+Subject: [PATCH 1/2] exec: do not leave bprm->interp on stack
+
+If a series of scripts are executed, each triggering module loading via
+unprintable bytes in the script header, kernel stack contents can leak
+into the command line.
+
+Normally execution of binfmt_script and binfmt_misc happens recursively.
+However, when modules are enabled, and unprintable bytes exist in the
+bprm->buf, execution will restart after attempting to load matching binfmt
+modules. Unfortunately, the logic in binfmt_script and binfmt_misc does
+not expect to get restarted. They leave bprm->interp pointing to their
+local stack. This means on restart bprm->interp is left pointing into
+unused stack memory which can then be copied into the userspace argv
+areas.
+
+After additional study, it seems that both recursion and restart remains
+the desirable way to handle exec with scripts, misc, and modules. As
+such, we need to protect the changes to interp.
+
+This changes the logic to require allocation for any changes to the
+bprm->interp. To avoid adding a new kmalloc to every exec, the default
+value is left as-is. Only when passing through binfmt_script or
+binfmt_misc does an allocation take place.
+
+For a proof of concept, see DoTest.sh from:
+http://www.halfdog.net/Security/2012/LinuxKernelBinfmtScriptStackDataDisclosure/

+Subject: [PATCH 2/2] exec: use -ELOOP for max recursion depth
+
+To avoid an explosion of request_module calls on a chain of abusive
+scripts, fail maximum recursion with -ELOOP instead of -ENOEXEC. As soon
+as maximum recursion depth is hit, the error will fail all the way back
+up the chain, aborting immediately.
+
+This also has the side-effect of stopping the user's shell from attempting
+to reexecute the top-level file as a shell script. As seen in the
+dash source:
+
+ if (cmd != path_bshell && errno == ENOEXEC) {
+ *argv-- = cmd;
+ *argv = cmd = path_bshell;
+ goto repeat;
+ }
+
+The above logic was designed for running scripts automatically that lacked
+the "#!" header, not to re-try failed recursion. On a legitimate -ENOEXEC,
+things continue to behave as the shell expects.
+
+Additionally, when tracking recursion, the binfmt handlers should not be
+involved. The recursion being tracked is the depth of calls through
+search_binary_handler(), so that function should be exclusively responsible
+for tracking the depth.
