Two Vulnerabilities Provide Root Access on Linux

Filed under

Security

Two new vulnerabilities affecting Linux were uncovered this week that could potentially be used by malicious hackers to gain root privileges.

One vulnerability, which was reported on Tuesday by security firm VSR, arises from a flaw in the implementation of the Reliable Datagram Sockets protocol (RDS) in versions 2.6.30 through 2.6.36-rc8 of the Linux kernel.

Known as CVE-2010-3904, the bug could allow a local attacker to issue specially crafted socket function calls to write arbitrary values into kernel memory and thereby escalate privileges to root, giving the attacker "superuser," administrator status.

Linux Kernel Update

pcworld.com: A new update to the Linux kernel adds a raft of security features, driver support, and other enhancements without increasing the overall size of the kernel at all.

That's a rarity, given that enhancements in each update have tended over the years to increase the kernel's size. This time around, though, there are a number of improvements that will be visible to users, but without any extra mass.

It won't be long before this new kernel is integrated into most popular Linux distributions. Here are some of the highlights of what users can expect.

Windows XP: Your upgrade experiences

I think more media attention needs to be brought to Linux [an open-source operating system] nowadays. I've tried many platforms and have found Lubuntu in particular to be a very sophisticated and extremely lightweight operating system. Even on computers with as little as 512MB of RAM the system boots, runs programs and shuts down like a bullet. Read more

Ondemand vs. Performance CPU Governing For AMD FX CPUs On Linux 3.17

In the tests shared yesterday of looking at the AMD FX-9590 CPU on Linux and other CPU benchmarks from this weekend, some Phoronix readers raised concerns about the CPU scaling governor differences between the AMD and Intel hardware. The AMD FX CPUs continue to use the CPUfreq driver by default to handle their scaling while modern Intel CPUs have the new Intel P-State driver. Beyond the Intel-specific P-State vs. CPUfreq, the AMD CPUs generally default to using the "ondemand" governor while with Intel desktop CPUs on P-State it generally ends up with the "performance" mode. Some Phoronix readers found performance vs. ondemand differences to be unfair, but for AMD FX CPUs, there isn't much of a difference in our common CPU torture test benchmarks found in the Phoronix Test Suite.

Google Sends Invites for September 15 India Event; Android One Launch Likely

Google has sent invitations for an event in India on September 15. While the invite itself says "More details closer to the date!", it is expected that the much-awaited Android One smartphones will make their debut at the event. Android One was announced back in June at Google I/O with India's Karbonn, Micromax, and Spice the confirmed launch partners, though more Indian companies have reportedly joined the list since then.
