Apache Software Foundation has released security updates to address vulnerabilities in Apache Tomcat versions 9.0.0.M9 to 9.0.9, 8.5.0 to 8.5.31, 8.0.0.RC1 to 8.0.51, and 7.0.28 to 7.0.86.

A remote attacker could exploit one of these vulnerabilities to obtain sensitive information.

Administrators need to review the Apache security advisories for CVE-2018-8037 and CVE-2018-1336 and apply the necessary updates.

Debian 9 “Stretch” was released over a year ago and since then, the wildly popular Linux distribution has been downloaded by countless users.

Today, the 5th “point” release becomes available. In other words, Debian Linux “Stetch” has reached an important milestone — version 9.5 stable. The operating system is always improving with security updates and bug fixes, and 9.5 is no exception here. In fact, it includes a patch for Spectre V2. Also of significance, the Debian Installer has been given an update.

“The Debian project is pleased to announce the fifth update of its stable distribution Debian 9 (codename ‘Stretch’). This point release mainly adds corrections for security issues, along with a few adjustments for serious problems. Security advisories have already been published separately and are referenced where available,” says The Debian Project.

The project further says, “Please note that the point release does not constitute a new version of Debian 9 but only updates some of the packages included. There is no need to throw away old ‘stretch’ media. After installation, packages can be upgraded to the current versions using an up-to-date Debian mirror. Those who frequently install updates from security.debian.org won’t have to update many packages, and most such updates are included in the point release.”

Quite frankly, the number of updated packages is quite large — if you are a Debian user, I urge you to read the full changelog here. You can see the long list of changes, not only for 9.5, but all “Stretch” releases.

Despite the developers saying you don’t have to create new install media, if you still want to do so, you can grab an ISO here.

1. Affordable

The most obvious benefit is that it is free and so are its applications. It saves me money as upgrading or installing applications will not cost me a dime unlike Windows which I have to buy each and every component, application and even some upgrades. This also means that I can freely share the OS among friends without it being illegal. The Linux system is more secure than Windows meaning that it is less prone to virus infections. This means that means that I do not incur frequent expenditures on anti-viruses which further make it affordable.


2. Security and Stability

There few occasions of system crashes with a Linux OS because the core operating systems is separate from the GUI that hosts the applications. In windows the core system and the applications are integrated such that when an application crashes it can lead to the crash of the whole operating system. For Linux however, the incomplete integration means that an application crashes without affecting the OS.


Linux is an extremely stable system which offers the benefit of less rebooting. Application crashes do not affect the whole system and one just needs to restart the specific application unlike Windows which requires rebooting. Linux has the advantage of being compatible with various file systems such that it can open over a 100 types of files. Windows on the other hand can only read its own file systems. This makes Linux more versatile especially if since I frequently extract data from a hard drive formatted on a different computer.

Linux offers more security for my data than Windows. Being an Open Source program any attempt to access data is easily detected and disabled.  With Windows the government and also other spies can easily access your data.


3. Expansive support

Linux has three commercial support providers which are Red Hat, Novell and Canonical. These provide 24/7 support for critical applications and business services. This plus the worldwide community support it being an open source program offers me  the best experience as the forums are upbeat and very resourceful.

As you know that, Linux is a robust operating system. Therefore, it works deeply on the hardware more. Rather, it has less effect on the software front. Therefore, if you put the wrong commands on Linux platform, then your computer hardware will damage or even, it will push the hardware into the eternal sleep as well. Therefore, you should make yourself more careful for using the wrong commands on Linux platform. Actually, Linux is a kind of operating system, which will not harm any hardware without any reason.

However, if Linux gets the wrong commands, then it will immediately strike back with a great thud on the hardware and instantly destroy the whole hardware system. One interesting point to tell you that if you are curious about for testing these wrong commands on Linux system seriously, then you can use the virtual machine, which will never do any harm to your computer hardware as well. However, never try to test these dangerous commands in any physical machines also.

Delete everything:

The command rm -rf / is responsible for the deletion of every files in the system. Moreover, this command is dangerous when you have a bunch of important files in your computer, then it will work venomously to wipe out all the files from your machines when you put this command to work. Eventually, the deleted files will not be recoverable at any cost. Once, it is done, then you will lose it forever and there will be no chance for any recovery even with the help of the data recovery software as well. The command part rm means removing the following files or folders whereas the command segment -rf means to remove all the files and folders without prompting you as well.

Fork bomb:

The command : (){ : |: & };: is a kind of Linux command which will destroy the CPU time and memory as well. It is very much dangerous for any computer machine. The reason is that it works like a replication way which means that your files in Linux will be duplicates in many times until CPU time and memory freezes as well. The main effect of this command will freeze your computer. Actually, it is a kind of denial-of service attack. One thing, you should not use this command for fun in any Linux machine. As it will destroy computer memory and hard disk heavily as well. When the CPU time and memory lost due to this command, then you will find that some programs are also mal-functioning due to it as well.

Formatting the hard disk:

It is a kind of command, which will wipe out your wholehearted disk space without leaving any trace of file or folder as well. Actually, the command mkfs.ext4 /dev/sda1 which will delete your computer hard disk fully. Therefore, there will be no chance for having any file trace as well. Moreover, you can expect the total whitewash in your Linux machine.

Actually, you can expect a different kind of formatting hard disk. The reason is that it will bring the hard disk in a factory-formatted disk. Therefore, you will get the deeper cleaning of your hard disk in such a way that as if you buy the new hard disk from the local market as well. However, you should never think that you would use this command for formatting your hard disk. The reason is that you should not try it in your Linux machine alone and you stay away from it.

Writing directly into the hard disk:

The command command > /dev/sda is very much dangerous for any Linux machine. The reason is that when this command will work on the Linux platform, then it will write directly into hard disk and it will damage the file system of the operating system as well. Moreover, you have to understand well before it strikes in your machine. Even, you will see that this command will make your directory structure more vulnerable as well.

Moreover, the default setting of the hard disk sector binding will get dislodge. Therefore, you will get the inconsistent data result from your Linux machine. Actually, after putting the command in Linux, you will have a little time to feel what is going to happen next. Therefore, the damage processing will be happen in the quick succession before you understand it fully.

Therefore, the list of the deadly commands will never give you a peaceful feeling when you consciously or unconsciously put it in your Linux machine as well. Even, if you commit the mistake for having these deadly commands work on your Linux machine, then you have to reinstall the new operating system in your machine as well.

Today, the Debian Team has announced the first update of the latest stable distribution Debian 7 Wheezy. In this update we can find some security corrections and few more adjustments for other big problems.  Security advisories were already published separately and are referenced where available.

This update does not constitute a new version of Debian 7 and only updates some of the packages included.  You don;t need to  throw away your 7 CDs or DVDs but only to update via an up-to-date Debian mirror after an installation, to cause any out of date packages to be updated.

Those who frequently install updates from security.debian.org won’t have to update many packages and most updates from security.debian.org are included in this update.

New installation media and CD and DVD images containing updated packages will be available soon at the regular locations.

Upgrading to this revision online is usually done by pointing the aptitude (or apt) package tool (see the sources.list(5) manual page) to one of Debian’s many FTP or HTTP mirrors. A comprehensive list of mirrors is available at: http://www.debian.org/mirror/list
