Canonical Ltd has issued updates for its Kernel package to plug multiple security holes. A security issue affects the following Ubuntu releases:

=> Ubuntu 6.06 LTS
=> Ubuntu 7.04
=> Ubuntu 7.10
=> Ubuntu 8.04 LTS

This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu.

Description

IPsec protocol stack did not correctly handle fragmented ESP packets. A remote attacker could exploit this to crash the system, leading to a denial of service.(CVE-2007-6282)

The 64bit kernel did not correctly handle hrtimer updates. A local attacker could request a large expiration value and cause the system to hang, leading to a denial of service. (CVE-2007-6712)

The ia32 emulation under 64bit kernels did not fully clear uninitialized data. A local attacker could read private kernel memory, leading to a loss of privacy. (CVE-2008-0598)

A race condition was discovered between ptrace and utrace in the kernel. A
local attacker could exploit this to crash the system, leading to a denial
of service. (CVE-2008-2365)

The copy_to_user routine in the kernel did not correctly clear memory destination addresses when running on 64bit kernels. A local attacker could exploit this to gain access to sensitive kernel memory, leading to a loss of privacy. (CVE-2008-2729)

The PPP over L2TP routines in the kernel did not correctly handle certain messages. A remote attacker could send a specially crafted packet that could crash the system or execute arbitrary code. (CVE-2008-2750)

Gabriel Campana discovered that SCTP routines did not correctly check for large addresses. A local user could exploit this to allocate all available memory, leading to a denial of service. (CVE-2008-2826)

How do I update Kernel package?

Open terminal and type the following two commands:
$ sudo apt-get update
$ sudo apt-get upgrade

After a standard system upgrade you need to reboot your computer to effect the necessary changes:
$ sudo reboot

Ubuntu 'reaping Linux dividend'

Red Hat and Novell decided not to challenge Microsoft on desktop PCs. However, Canonical Ltd is getting ready to release a new version of Ubuntu on Thursday. According to Mark Shuttleworth:

The public perception of open source software is changing fast. French police force was currently deploying 50,000 Ubuntu-powered machines, while Spanish education authorities were rolling out 500,000 desktops with the OS. Hardy Heron also has improved support for multimedia, including photo editing, music sharing and video playback. It's a favorite version of Linux both for specialists and one that specialists would recommend to a cousin, aunt or uncle who want to have a stable desktop internet experience. There are other versions of Linux that are better for a particular purpose - but Ubuntu strives to be a general platform that is secure and self-maintained.

Ubuntu Linux Getting Ready For Average User

The latest beta of the popular Ubuntu Linux distribution offers updated features and good support for new Linux user. It appears that Ubuntu is getting ready for masses. From the article:

If there is a single complaint that is laid at the feet of Linux time and time again, it's that the operating system is too complicated and arcane for casual computer users to tolerate. You can't ask newbies to install device drivers or recompile the kernel, naysayers argue.

Of course, many of those criticisms date back to the bad old days, but Ubuntu, the user-friendly distribution sponsored by Mark Shuttleworth's Canonical Ltd., has made a mission out of dispelling such complaints entirely.

Canonical Ltd the creator of Ubuntu Linux has released a new software called Bazaar. It is a distributed version control system available under the GPL that reduces barriers to participation in your project. If you can run Python 2.4, then you can run Bazaar.

There are many really good VCS tools such as Subversion and Git. Bazaar is a decentralized revision control system. Revision control involves keeping track of changes in software source code or similar information, and helping people work on it in teams.Bazaar features
=> Reliable
=> Ease of use
=> Portable software (Works on *nix / Windows)
=> Flexible
=> GPL Code
=> Good performance
=> Safe with your data etc

The program is simple to deploy. It doesn't require a dedicated server. Any Web server that includes ftp will work as a Bazaar server. Canonical also states that because developers can commit their code locally whenever they want, they're less dependent on the central code base.
