Security flaws in Guest Accounts of Ubuntu 11.10

The Ubuntu 11.10 is already available to download in official site. AS it is a most updated OS, i would like to know are there any security flaws?

Released updates address a number of rather serious security vulnerabilities. At least two of these allow an attacker to be exploited to execute code with root privileges. The areas concerned are the implementation of CIFS and improper management of the Bluetooth stack. Another vulnerability affects the Ext4 file system: due to a mishandling of the missing inode, may allow attackers to cause a crash.

In the operating system Ubuntu is a dangerous vulnerability has been discovered. It can be used to obtain root privileges. An already available for Ubuntu patch fixes the problem.

On this occasion, between eleven correct vulnerabilities do not miss anything: the lowering of the level of privacy, system crash, privilege escalation and arbitrary code execution. For server versions that count 70% of installations LTS is not just the maximum. The version is available as an upgrade 2.6.32-35, 2.6.38-12, while as regards the need to manually installed. To correct the severity of the flaws is very important to align the systems installed.

Intrigued by making Canonical's latest plans to Ubuntu aggressive corporate customers tasty, have 5-year support for the LTS version, etc., I look at the features of the latest version of Ubuntu 11:10 viewed on the homepage.

• A integrated firewalls well as virus protection.
• Automatic security updates
• Defense against viruses
• Anti-phishing
• File encryption
• Password protection
• Built with security in mind
• The installation of software works only as super user (root), additional protection by AppArmor.

So nothing with virus scanners. As a rule, on a pure Linux system to Data scanner needed. Nevertheless, I find the phrase "built-in .. virus protection "borderline, even though they will probably mainly be due to marketing reasons. The reader is ignorant here suggests a more integrated antivirus solution, especially since Ubuntu is aimed at beginners or passengers in transit. I personally would find better "secure by default" or something along these lines.

I do not quite understand what you're getting. "Protection" means "protection" and not "scanner". Strictly speaking, the protection has been denied if the scanner strikes. In the professional area, no one will run on a computer after the fact viruses / trojans / etc. found (and removed) were. Indeed, one can never know what can not be found. Therefore, in principle a clean image is played back.
