Linux Kernel "request_key_auth.c" and "namei.c" Denial of Service

Multiple vulnerabilities were identified in Linux Kernel, which could be exploited by local attackers to cause a denial of service or bypass certain security restrictions.

The first issue is due to a memory leak error in "/security/keys/request_key_auth.c", which could be exploited by malicious users to cause a denial of service.

The second vulnerability is due to a memory leak error in "/fs/namei.c" when the CONFIG_AUDITSYSCALL option is enabled, which could be exploited by malicious users to cause a denial of service.

The third flaw is due to an error in the file "drivers/char/drm/drm_stub.c" that does not properly validate "debug" sysfs permissions, which could be exploited by local attackers to bypass certain security restrictions and enable drm debugging.

Linux: 2.6.14-rc4, Final Release Candidate

Linus Torvalds announced 2.6.14-rc4, "the final -rc before a 2.6.14 release." The 2.6.14 merge cycle began with the release of the 2.6.13 kernel on August 28'th [story], allowing for two weeks of time during which large changes were allowed into the mainline kernel [story]. For the past month, primarily only bug fixes have been accepted as the kernel developers have worked toward a stable release. In his email, Linus summarized the changes in the latest release candidate:

"In the diffstat, most of the changes are one-liners, with the main exceptions being some sparc64 work (fix user-space corruption due to FP save/restore) and the new Megaraid SAS driver. There's some networking fixes, and a couple of driver updates (scsi: aacraid, net: cassini, and watchdog: pcwd_pci). Along with a x86-64 suspend/resume page table corruption and some new defconfig files for ARM, that rounds out the bigger chunks."

Dna Studies Suggest Emperor Is Most Ancient of Penguins

  • New York Times; By CARL ZIMMER (Posted by tadelste on Oct 11, 2005 6:24 AM EDT)
  • Story Type: News Story; Groups: Gentoo
Penguins are some of the most improbable animals on the planet. They have wings and feathers but cannot fly. They are not fish, but they have been recorded as deep as 1,755 feet underwater. And the most improbable is the emperor penguin, which waddles across 70 miles of Antarctic ice to reach its breeding grounds. New research on penguin DNA suggests that the emperor also has the most ancient lineage of living penguins.

Efficient Linux Mapping tool for MPI Blue Gene

A high-performance computing (HPC) Linux service tool for efficient mapping of Message Passing Interface (MPI) tasks to the IBM Blue Gene/L Supercomputer. The algorithms used for mapping are based on the paper Optimizing Task Layout on the Blue Gene/L supercomputer. [pdf] In this paper it talks about the extensive amount of data transmitted between processors for producing maps and the challenge of minimizing the communication time.

Critics don't like Microsoft gift

A controversial new partnership between the South African government and the world’s leading software company, Microsoft, is at the centre of a heated debate about the best way to roll out IT access to poor communities.

The memorandum of understanding signed by the Department of Communications parastatal the Universal Services Agency (USA) and Microsoft aims to roll out free Microsoft software and training to telecentres in all 284 municipalities over three years.

However, critics claim that the agreement contradicts the Cabinet-level open-source strategy that was approved in June 2003.

Should Linux vendors think differently?

No matter how many strides Linux makes toward desktop acceptance, we're still a long way from the day when we'll see the free OS become a true drop-in replacement for the commercial systems we use now. Case in point: Last week, the folks at Novell were kind enough to send along a copy of their latest OS release, Suse Linux 10.0. I've always thought Suse had an edge over Red Hat in the UI department. Plus, Novell describes this edition of its product as a home-user version targeted at "hobbyists and enthusiasts." So, naturally, I figured I'd install it on my desktop PC at home.

Review: Ubuntu 5.10 Breezy Badger

The Ubuntu 5.10 release, also known as Breezy Badger, is not drastically different from the previous Ubuntu release, 5.04 Hoary Hedgehog, but it is an excellent distribution that is well worth a look for any user interested in a Linux distro for the desktop or server.

With 'Free' Lure,

It's hard to compete with "free."

Some rivals of Web search powerhouse Google Inc. have already learned that lesson. Now, companies in a broader set of industries are grappling with how Google's ad-fueled expansion could potentially make it harder for them to charge for consumer services and products.

Opening Windows

For three decades, the executive leadership at Microsoft Corporation has maintained a firm consensus on how to encourage innovative software development: you pay for it. User feedback, while helpful, is simply no match for the mighty dollar. Cash for code is king. “Who can afford to do professional work for nothing?” asked Microsoft founder Bill Gates rhetorically in a 1976 missive framing Microsoft’s worldview. Titled, “An Open Letter to Hobbyists” (see the sidebar of the same name to read the original letter in its entirety), the essay was, in essence, a cease and desist letter aimed at Altair aficionados who, according to Gates, were guilty of purloining Microsoft source code without paying for it. “Most directly, the thing you do is theft,” wrote Gates.

Hacks From Pax: Security Enhanced Linux and Mandatory Access Control

Security Enhanced Linux, or SELinux, is an exciting security project that is reaching maturity and poised to revolutionize the way Linux security administration is performed. Originally developed by the National Security Agency and released as an open source project, but now breaking into the mainstream in Red Hat, Fedora, Gentoo, and the new release of EnGarde Secure Linux 3.0, it incorporates Mandatory Access Control into a base Linux system. This is a revolutionary advance, but is also very different from the standard Linux security model. This week in Hacks From Pax, I'll provide a basic introduction to the philosophy behind SELinux, and explain how it can add a powerful layer of security to your Linux system.

Old school cuts ties with Windows

  • (Posted by ubuntu4all on Oct 10, 2005 5:44 PM EDT)
In July 2005, Warrington contacted Sirius, a local IT consultancy that specializes in providing open source software solutions. By the end of the summer break, Sirius project manager John Spencer had helped the school replace the aging Windows network with a cutting-edge Linux thin-client network that consists of 28 workstations and a server running the Linux Terminal Server Project (LTSP). The new system cost less than £15,000, which Warrington estimates is about 60% of the cost of a Windows equivalent, with no expensive licensing fees.
