commit 6f35f6deb5ca7daebe289f86477e061ce3ee5f46
Author: Matt Caswell <matt@openssl.org>
Date:   Thu May 5 11:10:26 2016 +0100

    Avoid some undefined pointer arithmetic
    
    A common idiom in the codebase is:
    
    if (p + len > limit)
    {
        return; /* Too long */
    }
    
    Where "p" points to some malloc'd data of SIZE bytes and
    limit == p + SIZE
    
    "len" here could be from some externally supplied data (e.g. from a TLS
    message).
    
    The rules of C pointer arithmetic are such that "p + len" is only well
    defined where len <= SIZE. Therefore the above idiom is actually
    undefined behaviour.
    
    For example this could cause problems if some malloc implementation
    provides an address for "p" such that "p + len" actually overflows for
    values of len that are too big and therefore p + len < limit!
    
    Issue reported by Guido Vranken.

Comment 1 Marcus Meissner 2016-06-01 15:45:49 UTC 
The patch applies partially at least to 0.9.8j too.

I am not enitrely convinced we need it, not sure if it is ioptimized away or not.

Comment 3 Vítězslav Čížek 2016-08-08 15:20:40 UTC 
Many of the hunks don't apply, because we missing some hardening commits, for 1.0.1 eg:
https://github.com/openssl/openssl/commit/40f26ac782157ceeafc986e3e91429099c0f878d
https://github.com/openssl/openssl/commit/89c2720298f875ac80777da2da88a64859775898
Comment 5 Marcus Meissner 2016-09-22 09:53:24 UTC 
There are two ways this could be a problem.

- In memory layouts where allocations are close to the top of the address space, 
  there could we wrapping.

  => I am kind of sure we do not have such setups on our platforms

- The compiler might optimize it away. I think this is NOT happening, but to confirm I would need to disassemble all libssl versions and check all the pieces of code.
