[RndTbl] Fw: [SECURITY] Fedora 36 Update: openssl-3.0.8-1.fc36

[Adam Thompson]

Bob Beck et al. from the OpenBSD project already "secured" OpenSSL, with the result being called LibreSSL.  It's drop-in compatible for many applications, but does require recompiling.  That team did a number of presentations on it, and apparently you can still hear the swearing echoing late at night when it's quiet...

The OpenSSL team, however, appear to be rather resistant to help.  Serious NIH syndrome.  Also they're more focused on preserving backwards compatibility than correctness or security.  And also don't respond well to criticism, from what I've seen.

All the large orgs you mentioned already have their own OpenSSL-replacement projects in-house, some of them public.  None of those are even remotely drop-in replacements, they're re-imagninings of what a secure-connection library should be.

As if we didn't already have enough issues with OpenSSL, what with
buffer overrun vulnerabilities in new/recent code*, and more direct
coding flaws (pointer free/dereference and such) that were recently
announced**.

You'd think with the combined wealth and resources of Alphabet/Google,
Apple, and Microsoft, they'd find it in their best collective
self-interest to fund a project to replace this garbage with some, you
know, actually secure code.

Sigh!

    (Many of the above do mention the side-channel attack too.)
