Re: VUPEN Security Research - Adobe Flash Player RTMP Data Processing Object Confusion (CVE-2013-2555)

Your proposition was that developers will always make mistakes and
introduce stupid problems, so a QA team/process is necessary. While I agree
that there should be a QA/'audit' at some point, it shouldnt be the stage
that is relied on. Applications that are flawed from the design stage
onwards will become expenditure blackholes, especially after going through
any QA process which should highlight these.

Potentially yes, but most of the larger companies appear to already do
this. A quick search through google shows that Oracle atleast already have,
and/or are actively hiring security engineers involved with Java (for
example).

Flaws will always pop up and I think we may now be bordering on discussing
what counts as negligence in some cases. Your 5-chained-0day-to-code-exec,
in my opinion, does not count as negligence and comes from the developer
effectively not being a security engineer, but doing the job of a
developer. In my opinion we are not at the stage in industry where we can
consider/expect any developer to think through each implication of each
feature they implement, without a strong security background as much as we
may appreciate it. Negligence in my opinion of security vulnerabilities is
having obvious format string bugs/buffer overflows when handling user input
for example, or incorrect permissions, or just a lack of consideration to
obvious problems. Developer training should pick up on the obvious bugs, or
atleast give developers an understanding of how to handle users/user input
in a safe manner, and know the implications of not doing so.

I think the definition of 'needless staff' highly depends on whether you
want 'vulnerable software'.

Educating current developers is absolutely a good idea, but still not
foolproof. The bottom line is that if you want safe software, you need
to invest in proper development. As far as I am concerned, for large
companies like Adobe and Oracle, where software bugs in your product
have a direct impact on the safety of your customers, that involves
hiring specialized staff.

     Yes, a better idea would be to educate and inform developers. At a
     business level atleast this will a) save extra expenditure on
needless
     staff  and extra departments b) result in faster turn arounds as
there's
     then less time needed for remediation. At a technical level, it will
     atleast result in less 'dumb' bugs (assuming training and education
is
     effective and relevant).
     I think at this point expecting software to have 0 flaws or being
under
     the illusion that software will ever be flawless in it's current
state
     is like wishing really hard before bed every night that genetics and
     evolution will make you a unicorn.

       I am just saying that developers and designers make mistakes and
       that there is no getting around that. Rather than relying on the
       benevolent 0day researchers from the sky publicly disclosing their
       vulnerabilities, more responsible QA testing within the company
will
       prevent many of these vulnerabilities from occurring in the first
       place. Or do you have a better idea?
