OT: looking for help remembering name/info about security bug

[Stan Sieler]

I've received a couple of suggestions, thanks, but none seem right.

BTW, I'm sorry (Liam) that I didn't make it clearer that it was absolutely
a software bug, which excludes Spectre, Rowhammer, Meltdown.

Aside: the Meltdown and/or Spectre patch to macOS hurt performance ... the
elapsed time to compile 500 programs increased by about 12%.  (At the time
of the patch, I tested (properly) before and after the patch ... then
forgot to publish, and since misplaced my notes.)

Although I mentioned 'code', I should have been more specific: C (or,
possibly, C++), but definitely no other language.

I don't recall it being a buffer overflow.

I *think* it was some kind of authentication failure (e.g., incorrectly
reporting "ok"), but I'm not sure.

I do know I wrote a several page article about it, and how certain coding
practices led to it, but I can't *find* the article now  :(
(not published)
My guess of 4-6 years ago is possibly narrower than it should be, but I'm
not sure.

My hope is that by being reminded of the vulnerability name, I can search
my computer, and backups, for text files containing that name :)
(Or the name of function associated with the problem.)

thanks,

Stan
