Unbound service routinely stopping/crashing following 20.7.7 update

[mimugmail]

Just install the patch previously posted here

For now, I *think* I've setup a monit test to restart unbound if it crashes. Never used monit before, so we'll see if I did it right...

Hi,

I'm also newbie, and also having the same issue with the unbound service stopping. Where you able to create a monit service to restart unbound when stop? can you share the configuration?

Thank you very much

I'm newbie myself but found this topic in documentatin: https://docs.opnsense.org/manual/monit.html#example-1

As I said before i'm newbie (learning with an opnsense at home), and I don't know which ''condition'' should I put to test that unbound is working and for the ''service settings'' which statements to put on ''PID File'', ''Start'' and ''Stop''.

Regarding the patch, i though it was good idea to learn how to use monit to restat a service that stop

thanks ; opnsense-revert -r 20.7.6 unbound did the trick for me as well

Please upgrade rather than downgrade :-)

New Unbound version (1.13.0) was released to deal with CVE issues, patch (1.13.0_1) is minor and keeps those improvements:

Here's the latest Unbound revision 1 from FreeBSD ports to try:

# pkg add -f https://pkg.opnsense.org/FreeBSD:12:amd64/20.7/misc/unbound-1.13.0_1.txz

Edits: Include version and package information

[Mks]

for the record,

I upgraded to 20.7.7_1 last week and immediately applied the patch:

# pkg add -f https://pkg.opnsense.org/FreeBSD:12:amd64/20.7/misc/unbound-1.13.0_1.txz

No issues identified, everything works.

Same issue here, unbound keeps crashing. I tyed the opnsense-revert thing, we'll see if it holds

For now, I *think* I've setup a monit test to restart unbound if it crashes. Never used monit before, so we'll see if I did it right...

Meanwhile I tried monit for the first time as well.
I *think* also I got it, but it took me a lot of tries, so for those who might be even more lost than I am, here is what I did in the monit>settings>service settings : add a new service as you can see in the attached picture.

Attached as well, in the monit>status you'll see it has found the proper process id.

I even stopped unbound and it got restarted within the 120 seconds of polling interval.

If you want to make it check faster, it happens on the first settings page, I think that is what would be the polling interval.

Couldn't find a way to get an email notification when the service gets restarted though... At least it restarts

Just to confirm I am observing this problem on 20.7.7 as well ("notice: sendto failed: Permission denied" 4 times in 4 days). I have reverted unbound to 1.12.0, waiting for a OPNsense fix (via 20.7.7_X or 20.7.8 ).

And YES, I am aware of the CVE-2020-28935, but this vulnerability is *only* CVSS-3 scoring 5.5 as this is *only* a local vulnerability that could create a DoS of the system Unbound/NSD is running on. A very limited security risk in my personal situation.

Thank you and stay safe.

Unbound crashes for me too.  Have not tried downgrading at this point.

One surprising thing was to see it does not  restart itself - I would imagine for key system services there would be some auto restart process.  Is there not such a thing in opnsense or is it disabled for unbound ?

On my system it does restart but after 5 crashes it triggers the HBSD SEGVGUARD which suspends processes for 600s after 5 crashes.

No, but you can add this via monit

[Spacefish]

affected by this as well.

15min ago someone release a fixed version of the unbound package: https://github.com/mat813/freebsd-ports/commit/95a05e89eda2ed7629addb4a28117e463b69eeb0

could we just get that upgrade via official update repos for OpnSense as fast as possible?

Looks like you missed the post above - see post #37

No service can restart itself by itself when it dead. Only an OS or an another service can do it.

Same issue here...
