Subject: All machines: Pointer guard testing update (Bug 15754, CVE-2013-4788).
Date: Thu, 26 Sep 2013 14:52:00 -0000	[thread overview]
Message-ID: <> (raw)

All machines,

The fix for CVE-2013-4788 (bug 15754) contains a regression
test to ensure that the pointer guard is both random and
changes between processes.

In order to create the test it was necessary to add a new
accessor macro POINTER_CHK_GUARD to allow the regression
test to locate and read the pointer guard value from outside
of the library.

I have added a POINTER_CHK_GUARD implementation for *all*
machines. You need not do any work at this point. However,
for some machines I wrote the implementation without testing
it e.g. stack guard was just before pointer guard so
POINTER_CHK_GUARD is the same code with a different offset.

My request is that you run the testsuite and verify that
tst-ptrguard1 and tst-ptrguard1-static pass. If they don't
pass please email me and we can work out what might be
wrong with your POINTER_CHK_GUARD implementation.
