I have updated my 1550 already 8).

...and found a serious bug in APPI updates making APCL work no more...

[Amir_Ayalon]

Hi Guys

we didn't see any bug in APPI. in fact there was no change in this region, so i'll be surprise if there is a bug.

As for why OpenSSL in not 1.1.1n. the issue was fixed within the same OpenSSL version.

[G_W_Albrecht]

I resolved the bug. Not a fault of the fixed firmware...

[G_W_Albrecht]

Very strange: For R80.10, HF is available based on JT_30 as Check_Point_R81_10_JHF_T30_743_MAIN_Bundle_T2_FULL.tar.

But on R81.10 JT_38, verify as well as install work perfectly:

Afterwards:

#cpopenssl versi

OpenSSL 1.1.1n  15 Mar 2022

But as only openssl-1.1.1n-1.cp996000002.....rpm gets installed that seems to be not an issue - but can CP confirm that this is supported ?

[Chris_Atkinson]

The wording of the SK is specific, it doesn't say T30 and above.

If you need this for T38 I would contact TAC and request it be ported for official support or await the future JHF which includes it.

[G_W_Albrecht]

As only cpopenssl is replaced, it should work with R81.10 JT_38 as well. Submitted the question as feedback in sk178411!

Thanks @G_W_Albrecht 
You are right 🙂
The HF for R81.10 T30 is also valid for R81.10 T38
sk178411 is updated accordingly, refer the note in 'Solution' section.

[G_W_Albrecht]

Yes, i just had received the reply from R&D !

[G_W_Albrecht]

R&D just released this statement:

"No changes were made to the cpopenssl module between General Availability (GA) Takes and Ongoing Takes of the Jumbo Hotfix Accumulators. Accordingly, this Hotfix also applies to Ongoing Takes."

sk178411 has been edited to reflect this.

Hello, 
does anyone have information how dangerouis this issue really is?
who has seen Check Point gateways freezing by this issue?
does it affect every Check Point installation when it is reachable via HTTPS from the outside/inside world?
or is it sufficient to surf a special crafted website and this will freeze the CP gateway?
in combination with HTTPS inspection, does it also strike or even more?

since special elicpic curve ciphers are causing this ... does it make sense to disable them?

Did Check Point already release a public advisory email to inform costumers and partners?

[Ethan_Schorer]

Hi Thomas,

AFAIK, we haven't yet seen the actual exploitation, but that doesn't mean that it hasn't or won't happen. By the description of the bug, the vulnerability is while reading the ECDSA extensions. Therefore, disabling them shouldn't have an effect as we're trying to understand what to use and that's where the exploitation takes place.

How dangerous? It is not a breach, but rather a Denial of Service, and this would happen when the gateway reads a client or server certificate (e.g. HTTPS Inspection reaching a web site with a malicious certificate).

As this is a public vulnerability with published exploits, Check Point highly recommends installing security fixes that we release.

HTH,

Ethan

[G_W_Albrecht]

R81.10 Jumbo HotFix - Ongoing Take 44 (22 March 2022) is already available including the HF:

Check_Point_R81_10_JUMBO_HF_MAIN_Bundle_T44_FULL.tgz

[G_W_Albrecht]

Jumbo Hotfix Accumulator for R80.20 starting from Take 208 is already available including the HF.

Sorry for bringing this old thread up. But I'm somewhat confused when it comes to Gaia Embedded / SMB. sk178411 links directly to R80.20.35 with buildnr: https://supportcenter.checkpoint.com/supportcenter/portal?action=portlets.DCFileAction&eventSubmit_d...

This build is higher than the "official" R80.30.35 listed in:

https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...

I suppose this means that if you are running 1500, 1600 or 1800 series on R80.20.35 or lower, you need to upgrade to minimum R80.20.35 with buildnr: 992002639 to be secure.

But what about those who are running R80.20.40, R80.20.50 or R81.10.00? I can't see anything in the R80.20.40, R80.20.50 or the R81.10.00 changelogs, or anything specific within sk178411 saying these versions are secure. I would think they all have the fix included as it was originally released as a new revision/build of R80.20.35, but some kind of confirmation on the topic would be nice.

What about the 1400 series that are still running R77.20.87. Are these vulnerable?

[G_W_Albrecht · Accepted solution]

Yes: you need to upgrade to minimum R80.20.35 with build 992002639 to be secure. All newer versions also include the fix (newer software package)

What about the 1400 series that are still running R77.20.87. Are these vulnerable? See the SK footnote:

• This issue does not apply to SMB appliances running Gaia Embedded R77.20.xx.

[RamGuy239]

@G_W_Albrecht 

I'm not sure how I managed to miss the part regarding R77.20. My bad. I just verified this by running "openssl version" and it looks like R80.20.40+ contains the updated OpenSSL version.

Thanks for the quick reply!

[G_W_Albrecht]

Correct - that made it very easy to fix in future versions as openssl is a complete package that can be just exchanged to a fixed version.
