Doing battle in the $9 billion Unix server market is not for the timid. Designing a competitive microprocessor is a costly business, and with the Unix market seemingly in permanent decline, it's easy to see why smaller players might drop out.

A flaw in the widely used BIND DNS (Domain Name System) software can be exploited by remote attackers to crash DNS servers and affect the operation of other programs running on the same machines. The flaw stems from the way regular expressions are processed by the libdns library that's part of the BIND software distribution. BIND versions 9.7.x, 9.8.0 up to 9.8.5b1 and 9.9.0 up to 9.9.3b1 for UNIX-like systems are vulnerable, according to a security advisory published Tuesday by the Internet Systems Consortium (ISC), a nonprofit corporation that develops and maintains the software. The Windows versions of BIND are not affected. BIND is by far the most widely used DNS server software on the Internet. It is the de facto standard DNS software for many UNIX-like systems, including Linux, Solaris, various BSD variants and Mac OS X. Attack can crash servers The vulnerability can be exploited by sending specifically crafted requests to vulnerable installations of BIND that would cause the DNS server process?the name daemon, known as "named"?to consume excessive memory resources. This can result in the DNS server process crashing and the operation of other programs being severely affected. To read this article in full or to leave a comment, please click here

A stealthy malicious software program is taking hold in some of the most popular Web servers, and researchers still don't know why. Last week, security companies Eset and Sucuri found Apache servers infected with Linux/Cdorked. If that malware is running on a Web server, victims are redirected to another website that tries to compromise their computer. Eset said on Tuesday it has now found versions of Linux/Cdorked engineered for the Lighttpd and Nginx Web servers, both widely used across the Internet. Marc-Etienne M. Leveille of Eset wrote that the company has found 400 Web servers infected so far, of which 50 are ranked in Web analytics company Alexa's top 100,000 websites.

Hewlett Packard and Japan's NEC will expand their existing partnership to develop high-end x86-based servers for cloud and Web applications. The companies said Thursday they will team up to accelerate research on HP's next generation of blade-based server systems, which the U.S. company is gradually introducing alongside its traditional Itanium Unix-based servers. They said their focus will be on creating x86 hardware that can run with the same reliability as the Unix products, which can then be employed in mission-critical roles running today's social networks, mobile applications and cloud-based services. HP is trying to catch up to rivals such as Amazon Web Services in the growing market for cloud services, while also stay competitive in hardware amid a general shift away from Unix. The company announced a strategy to pursue a hybrid cloud approach last year, based on a solution it is calling HP Converged Cloud. Last month it announced a new operating system for cloud computing, HP Cloud OS, built on the open-source hosting software platform OpenStack, but said initially the new OS will only run on its own hardware. The new partnership will aim to speed up the development of HP's Project Odyssey, which it first announced in 2011. The project is an attempt to integrate x86 server blades running Windows or Linux with its Itanium-based server lineup based on Unix. NEC said the companies will specifically focus on a system that HP has been developing for years called "DragonHawk," which is supposed to be able to incorporate both types of servers into a single cabinet but has been slow to materialize.

The past two years have already seen significant jumps in corporate Linux usage, but now it looks like that trend is continuing into a third year. To wit: While overall server revenue grew at just 3.1 percent and Windows server revenue increased just 3.2 percent in the fourth quarter of 2012 year-over-year, Linux experienced 12.7 percent year-over-year growth for the same period. Unix, meanwhile, was down 24.1 percent. That's according to the Linux Foundation, which on Wednesday released its 2013 Enterprise End User Report, focusing on Linux adoption. Conducted in partnership with Yeoman Technology Group, the annual study surveys members of the Linux Foundation's End User Council as well as other companies and organizations with sales of more than $500 million or at least 500 employees.

Percona continues to nip at Oracle?s heels, releasing a free version of the open-source MySQL 5.6 database with advanced features similar to ones in Oracle?s paid enterprise edition. The newly released Percona Server 5.6 features scalability, availability, backup, and security features similar to those found in Oracle?s MySQL 5.6 Enterprise Edition, which Oracle makes available only to customers who purchase a support contract. Percona Server 5.6, now available as a free download, also includes all the functionality of Oracle?s community edition of MySQL 5.6, released in February. Percona Server is designed to work with applications that would be too demanding for MySQL itself to support, said Peter Zaitsev, founder and CEO of Percona, a MySQL consultancy and software company.

It was 30 years ago today that the seeds were planted for both Linux and the open-source software movement, though neither is called that name by the man who help set both of them into motion, the irascible Richard Stallman. On that day, Stallman, then working at the Artificial Intelligence Lab at the Massachusetts Institute of Technology, posted on the net.unix-wizards and net.usoft newsgroups about an ambitious new project he was embarking on. ?Free Unix!? began the missive. ?Starting this Thanksgiving I am going to write a complete Unix-compatible software system called GNU (for Gnu?s Not Unix), and give it away free to everyone who can use it. Contributions of time, money, programs and equipment are greatly needed,? he wrote. To read this article in full or to leave a comment, please click here

Doing battle in the $9 billion Unix server market is not for the timid. Designing a competitive microprocessor is a costly business and, with the Unix market seemingly in permanent decline, it?s easy to see why smaller players might drop out. But Fujitsu says it?s in it for the long haul. Despite its small market share, the company is committed to developing its Sparc64 chip, and it thinks it has a role to play in keeping IBM from becoming too powerful, said said Noriyuki Toyoki, Fujitsu corporate senior vice president and the head of its server division. Noriyuki Toyoki IBM already has one giant ?cash cow? from its dominance in mainframes, he said. If IBM came to dominate Unix in the same way?it already has more than half the market, according to IDC?the industry and its customers would be worse off, according to Toyoki.

stinkymountain writes "Unix, the core server operating system in enterprise networks for decades, now finds itself in a slow, inexorable decline, according to Network World. Jean Bozman, research vice president at IDC Enterprise Server Group, attributes the decline to platform migration issues; competition from Linux and Microsoft; more efficient hardware with more powerful processor cores; and the abundance of Unix-specific apps that can now also run on competitor's servers."

Data security is something that most people don't want to think about. In our age of persistent connectivity, most data users, whether they are on a desktop, laptop or cell phone, connect to their data without thinking of the security risks of transmitting their data by connecting to a public network or an unsecured network of any kind. And most users think of data security in terms of malicious hacks on Windows and maybe a Mac once in a while. No one would ever think of screwing with Tux, he's so cute and all, and everyone loves good old open-sourced Linux, right? Well, no, yes and yes, but . . . I recently learned of the discovery of Mark Kikta's new take on an old tactic of creating a remote connection and a reverse shell that establishes persistence on a Linux server. This tactic is just one of the stages of a security breach, those being: reconnaissance, exploitation, elevation of privileges and the final one -- persistence. This particular technique is for demonstrating persistence, and assumes that the other steps have already been completed. His company, Viopoint, performs vulnerability assessment and network penetration testing of high-level enterprise networks with sensitive data. Kikta is a security consultant with the company (and former Linux engineer) who is a frequent speaker at information security and hacker conferences such as SecTorCa and various BSides events, Grr Con and others.
