-Subject: [PATCH] signal: always clear sa_restorer on execve
-
-commit 2ca39528c01a933f6689cd6505ce65bd6d68a530 upstream.
-
-When the new signal handlers are set up, the location of sa_restorer is
-not cleared, leaking a parent process's address space location to
-children.  This allows for a potential bypass of the parent's ASLR by
-examining the sa_restorer value returned when calling sigaction().
-
-Based on what should be considered "secret" about addresses, it only
-matters across the exec not the fork (since the VMAs haven't changed
-until the exec).  But since exec sets SIG_DFL and keeps sa_restorer,
-this is where it should be fixed.
-
-Given the few uses of sa_restorer, a "set" function was not written
-since this would be the only use.  Instead, we use
-__ARCH_HAS_SA_RESTORER, as already done in other places.
-
-Example of the leak before applying this patch:
-
-  $ cat /proc/$$/maps

-  $ ./leak
