Patching/Upgrading OpenSSL
-
VPN or SSH is best. Letting anyone even touch your GUI port remotely from an arbitrary IP is a bad thing. As this proves, it's not about a password, it's about exploiting the service itself. Custom ports won't hide you for long.
Are you saying VPN or SSH never had any security issues? Don't think so. VPN is also not convenient - does not work from many locations. SSH is better, but theoretically can be exploited as well - with the bug you do not know about (yet).
What is really missing for Web UI is the IP lockout if someone tries to brute force password.
It's really about the size of the attack surface you present to an adversary. The surface of SSH is small and WELL understood. The surface of a web GUI is large and not well understood.
Using an approach like FAIL2BAN to block IP's is useful, but it is far from sufficient protection.

There was a post on the FreeBSD forums about a mismatch between the libraries and the headers when configuring 'curl':
checking for OpenSSL headers version… 0.9.8 - 0x0090819fL
checking for OpenSSL library version... 1.0.1
checking for OpenSSL headers and library versions matching... no
configure: WARNING: OpenSSL headers and library versions do not match.I didn't see any headers in p1 (but then I just did a simple grep). It's likely that apache's configure doesn't check for consistency between the headers and the libraries.
Thanks so far. But could you please provide the URL of this issue. I would like to follow that topic. I have just searched the FreeBSD forum but did not find it.

Yes - Finding things at FBSD forums isn't easy.

FYI- 2.1.2 images are being tested now, so far no problems have been found, and every Heartbleed test we've tried has passed on them.
-
Good news.
What about rebuilt packages? Anyone testing them? I installed updates on 2.1.1 and have syslog-ng and vhosts broken, did not look in detail what is wrong yet…
-
Packages should be OK now, make sure to uninstall and then reinstall (not update) to ensure that it obtains the latest binaries.
If you do a firmware upgrade to 2.1.2 when it comes, they will be reinstalled properly there during the upgrade process.
If you have problems with specific packages post upgrade, start a new thread for each once individually.
-
I will first wait for 2.1.2, then troubleshoot packages. Both mentioned are not essential for now.
Snort and HAProxy-devel are good after update.Thanks again.

Thank you vey much. Yeah, finding things in the forums isn't easy. But the really unbelievable thing is that I have even been already subsribed to just this thread but did not see the curl/header sub-topic :).
Even at the risk of driving off-topic: To me as a non-expert the described header mismatch seems not that problemmatic because:
- curl just complains about the header mismatch, but I did not read any hint that it refuses to build or becomes unstable.
- it is detected in the environment of the question, whether a port is build against the base or the port version of openssl.
Or do you expect a subsequent patch with updated headers? Nevertheless, I am going to follow that thread.

I already commented on this on the issue tracker: Simply stop messing with packages without version bumps. This really is insane practice with absolutely no benefit whatsoever. Highly annoying at best, and worse yet very dangerous in cases like this. You just cannot have different packages with the same version installing different files depending on whether it's a first install, reinstall or upgrade, and you cannot have different packages with the same version installing different files depending on whether I install now or 10 minutes later. Ditto if the fixes affect configuration of the packages.
Stupid practice, drop it.

I replied on the ticket but it's better here:
We're looking into a way to do that but the version numbers are controlled by the FreeBSD port versions and not directly by us. Unless the FreeBSD port gets bumped, then we'd have to maintain our own copies of the port with our own custom version numbers and so on (a nightmare to keep synchronized). That is, unless there's another mechanism in the PBI build process that lets us set an additional number to signify a change.
The version number of the pfSense packages did change.
The problem is that the version of (for example) haproxy didn't change.
-
I must be missing something about PBI. The entire idea of "lets bundle separate libraries for each package so that they are self-contained" simply goes beyond me. This is not what you should do for exactly the reasons like this - instead of a simple single system library update you now go and need to recompile tons of packages. Where's the benefit in pretending that runtime dependencies don't exist? Exactly the same reason why bundling (either untouched or modified versions) of libraries in the source code - instead of compiling against the system ones - sucks from security POV. Coming from the Linux world - this is just on par with Windows. I seriously don't get it.
-
Not a topic for this thread, but see the mess that was 2.0.x and before packages for reasons why PBIs are better. The problem is primarily packages stomping all over each other with different versions of things like perl, openldap, etc. Uninstalling one package could render another one (or the base system) broken. There haven't been any such problems with PBIs, the only drawback is the extra space and sometimes duplicated files. If you want to open a new debate on that, start a fresh thread.
-
Well, frankly said, stuff that cannot be compiled against and run with what's shipped with the base system, well… either needs to be fixed or - failing that - simply should not be packaged and distributed. That's pretty much it. (Simplified, but that basically is the deal. People do not want to end up with 3 versions of openldap, 5 versions of perl and 7 versions of openssl just because some package has bugs and noone wants to fix it. Cannot see how's this beneficial to maintainers either - look at what happened now...
(And yeah, debating PBI would be worth its own topic.)
-
It's not that simple or easy, but may get better in the future after 2.2. Back seat driving is easy, actual solutions not so much. Still off topic for this thread.

Packages should be OK now
What is the easiest way to verify that the version of 2.1.1 that we get from mirror sites contains the updates?
make sure to uninstall and then reinstall (not update) to ensure that it obtains the latest binaries.
"Uninstall"? Is that best done by wiping out the pfSense partition? (…after backing up the configuration, of course...)
-
Well, that "back seat driving" is with some 10+ years of hands-on experience with source-based distros, such as Gentoo. Meanwhile, to get back on topic - so what's up with the upgrade/reinstall? So, the ports version has not changed, so the package manager just ignores the changed PBI even though you bump the version in the XML? ??? :o

That is for packages, not the base system. The base system requires an update to 2.1.2 (coming momentarily)

I don't recall the specific logic of the reinstall but the safest way to always ensure you have the correct version is to uninstall/reinstall the package. It's not worth splitting hairs over for something this important.

Just to be sure: If an update for the package is offered, I can install this directly. Or do I need to uninstall every package first?

You need only uninstall the affected package and reinstall that one affected package. No need to reinstall all. Or just do a firmware upgrade in a bit when 2.1.2 rolls out and the packages will reinstall themselves.
Apparently the former is not safe (as in, it produces completely invalid results, like here).
That guy's invalid results aren't the fault of anything but his broken "testing" methodology.
