QUESTION
e: this has been fixed through Spring Boot 2.6.5 (see https://github.com/spring-projects/spring-boot/issues/30243)
Since upgrading to Spring Boot 2.6.X (in my case: 2.6.1), I have multiple projects that now have failing unit-tests on Windows that cannot start EmbeddedKafka
, that do run with Linux
There is multiple errors, but this is the first one thrown
...ANSWER
Answered 2021-Dec-09 at 15:51Known bug on the Apache Kafka side. Nothing to do from Spring perspective. See more info here: https://github.com/spring-projects/spring-kafka/discussions/2027. And here: https://issues.apache.org/jira/browse/KAFKA-13391
You need to wait until Apache Kafka 3.0.1
or don't use embedded Kafka and just rely on the Testcontainers, for example, or fully external Apache Kafka broker.
QUESTION
With regard to the Log4j JNDI remote code execution vulnerability that has been identified CVE-2021-44228 - (also see references) - I wondered if Log4j-v1.2 is also impacted, but the closest I got from source code review is the JMS-Appender.
The question is, while the posts on the Internet indicate that Log4j 1.2 is also vulnerable, I am not able to find the relevant source code for it.
Am I missing something that others have identified?
Log4j 1.2 appears to have a vulnerability in the socket-server class, but my understanding is that it needs to be enabled in the first place for it to be applicable and hence is not a passive threat unlike the JNDI-lookup vulnerability which the one identified appears to be.
Is my understanding - that Log4j v1.2 - is not vulnerable to the jndi-remote-code execution bug correct?
ReferencesThis blog post from Cloudflare also indicates the same point as from AKX....that it was introduced from Log4j 2!
Update #1 - A fork of the (now-retired) apache-log4j-1.2.x with patch fixes for few vulnerabilities identified in the older library is now available (from the original log4j author). The site is https://reload4j.qos.ch/. As of 21-Jan-2022 version 1.2.18.2 has been released. Vulnerabilities addressed to date include those pertaining to JMSAppender, SocketServer and Chainsaw vulnerabilities. Note that I am simply relaying this information. Have not verified the fixes from my end. Please refer the link for additional details.
...ANSWER
Answered 2022-Jan-01 at 18:43The JNDI feature was added into Log4j 2.0-beta9.
Log4j 1.x thus does not have the vulnerable code.
QUESTION
I just upgraded an environment with nrwl from angular version 11 to 12 with two angular applications and several libraries. After update when I try to compile using optimization settings:
angular.json
...ANSWER
Answered 2022-Jan-31 at 19:50Reason of the issue
It is expected browserslist to return an entry for each version ("safari 15.2", "safari 15.3") instead of a range ("safari 15.2-15.3"). So, this is just a bug in the parsing logic of Safari browser versions which needs to be corrected and will be done soon in fixed versions of Angular 12/Angular 13. Link to details is here.
IMPORTANT UPDATE:
This is fixed in v12.2.16 and v13.2.1, please update if you are experiencing this issue. Users on v11 shouldn't be affected. Link to details is here. If you can not/do not want to update for any reason, then one of the workarounds below can be used.

Modify .browserslistrc

Forgive me for the newb question, but I am confused and obviously not understanding the fundamentals or explanations of how to use a Websocket server hosted over HTTPS
. Everything I find online leads me to have more questions than answers.
I have a Websocket server hosted on my HTTPS
website using Java code.
This is my WebsocketServer.java

ANSWER
Answered 2022-Jan-13 at 14:50Keep it easy.
Certs inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application, ...).
Simple conclusion: Dont implement any certs.
How-to get encrypted connections?As Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. A normal webserver (nginx, apache) takes care about the certs. It can be done in kubernetes (as ingress-controller) or with a "bare-metal" webserver.
Both of them should act as a reverse-proxy. This means: Your java-application doesn't know anything about certs. It has just unencrypted connections - like in your code on port 6868
.
But the client will not use this port. 6868
is only internally reachable.
The client will call your reverse-proxy at the normal HTTPS port (=443). The reverse-proxy will forward the connection to your java-application.

I was able to build a multiarch image successfully from an M1 Macbook which is arm64. Here's my docker file and trying to run from a raspberrypi aarch64/arm64 and I am getting this error when running the image: standard_init_linux.go:228: exec user process caused: exec format error
Editing the post with the python file as well:
...ANSWER
Answered 2021-Oct-27 at 16:58A "multiarch" Python interpreter built on MacOS is intended to target MacOS-on-Intel and MacOS-on-Apple's-arm64.
There is absolutely no binary compatibility with Linux-on-Apple's-arm64, or with Linux-on-aarch64. You can't run MacOS executables on Linux, no matter if the architecture matches or not.

I've got a docker image running 8.0 and want to upgrade to 8.1. I have updated the image to run with PHP 8.1 and want to update the dependencies in it.
The new image derives from php:8.1.1-fpm-alpine3.15
I've updated the composer.json
and changed require.php
to ^8.1
but ran into the following message when running composer upgrade
:
ANSWER
Answered 2021-Dec-23 at 11:20Huh. This surprised me a bit.
composer is correctly reporting the PHP version it's using. The problem is that it's not using the "correct" PHP interpreter.
The issue arises because of how you are installing composer.
Apparently by doing apk add composer
another version of PHP gets installed (you can find it on /usr/bin/php8
, this is the one on version 8.0.14).
Instead of letting apk
install composer for you, you can do it manually. There is nothing much to install it in any case, no need to go through the package manager. Particularly since PHP has not been installed via the package manager on your base image.
I've just removed the line containing composer
from the apk add --update
command, and added this somewhere below:
QUESTION
I'm building a server which uses feathers and socketio.
I'm trying to use feathers channels mechanism to notify relevant users (connections) on relevant events.
Users belong to groups, so upon connecting to the server, I add the connection to the appropriate channels.
Upon publishing, inside app.publish
,
I'm getting the right data and see that the connection is attached to the channel, but can't figure out how to listen to it on the client.
This is a simplified channels.js

ANSWER
Answered 2021-Dec-16 at 08:17Does a port need to be opened on the clients end to create the channel so the communication line is 2 ways. Perhaps javascript will have some code to open up the clients port.

QUESTION
ANSWER
Answered 2021-Dec-08 at 14:08macOS Monterey introduced AirPlay Receiver running on port 5000. This prevents your web server from serving on port 5000. Receiver already has the port.
You can either:
- turn off AirPlay Receiver, or;
- run the server on a different port (normally best).
Turn off AirPlay Receiver
Go to System Preferences → Sharing → Untick Airplay Receiver.
You should be able to rerun the server now on port 5000 and get a response:
