OpenSSL Security: A Year in Review

3 hours 10 min ago
The OpenSSL project looks at its security record for the last year. "The acceptable timeline for disclosure is a hot topic in the community: we meet CERT’s 45-day disclosure deadline more often than not, and we’ve never blown Project Zero’s 90-day baseline. Most importantly, we met the goal we set ourselves and released fixes for all HIGH severity issues in well under a month. We also landed mitigation for two high-profile protocol bugs, POODLE and Logjam. Those disclosure deadlines weren’t under our control but our response was prepared by the day the reports went public."

ownCloud Contributor Conference Announcements

Monday 31st of August 2015 11:03:08 PM
The ownCloud Contributor Conference 2015 (August 28-September 3 in Berlin, Germany) started off with some big announcements, including the publishing of the User Data Manifesto 2.0, the creation of the ownCloud Security Bug Bounty Program, and the release of the ownCloud Proxy app. "Designed for those of you who want your own private, secure “Dropbox” and don’t want the hassle of configuring routers, firewalls and DNS entries for access from anywhere, at any time, ownCloud Proxy is for you. It comes installed as an ownCloud community app in the new ownCloud community appliance, connects to relay servers in the cloud, and provides anytime, anywhere access to your files, on your PC running in your home network, quickly and easily. And, of course, you can grab it from the ownCloud app store and add it to an existing ownCloud server if you already have one running."

The 4.2 kernel has been released

Sunday 30th of August 2015 10:25:30 PM
Linus has announced the final release of the 4.2 kernel. "So judging by how little happened this week, it wouldn't have been a mistake to release 4.2 last week after all, but hey, there's certainly a few fixes here, and it's not like delaying 4.2 for a week should have caused any problems either." Headline features in this release include the security module stacking patches, the delay-gradient congestion-control algorithm, improvements to writeback management in control groups, a lot of important persistent-memory infrastructure, and more.

Starting in September, Chrome will stop auto-playing Flash ads

Friday 28th of August 2015 09:02:25 PM

Google has announced that, beginning September 1, Chrome will no longer auto-play Flash-based ads in the company's popular AdWords program. The post frames this as a move to improve browsing performance for users, and notes that most Flash ads are automatically converted to HTML5 already. Commenting on the news, The Register notes that the change should also offer some additional protection against malware delivered via Flash. Chrome will continue to auto-play Flash content in the main body of pages, however. The Register's story says the change is, in fact, just a modification of the default setting for plugin behavior, which already supports an option to disable plugin content not deemed "important." Mozilla, of course, blacklisted the Flash plugin in July, although that action only disabled the then-current, vulnerable release—which was subsequently updated.

KDE Sprints - who wins? (KDE.News)

Thursday 27th of August 2015 11:21:06 PM
KDE.News looks at KDE sprints and their benefits. The organization is doing some fundraising to help support its sprints, so it is trying get the word out about these code-focused events: "To start with, KDE sprints are intensive sessions centered around coding. They take place in person over several days, during which time skillful developers eat, drink and sleep code. There are breaks to refresh and gain perspective, but mostly sprints involve hard, focused work. All of this developer time and effort is unpaid. However travel expenses for some developers are covered by KDE. KDE is a frugal organization with comparatively low administrative costs, and only one paid person who works part time. So the money donated for sprints goes to cover actual expenses. Who gets the money? Almost all of it goes to transportation companies."

Grsecurity stable patches to be limited to sponsors

Thursday 27th of August 2015 04:29:07 AM
The developers of the Grsecurity kernel-hardening patch set have announced that, due to claimed ongoing GPL and trademark violations, the public distribution of the "stable" series of patches will stop. "We decided that it is unfair to our sponsors that the above mentioned unlawful players can get away with their activity. Therefore, two weeks from now, we will cease the public dissemination of the stable series and will make it available to sponsors only. The test series, unfit in our view for production use, will however continue to be available to the public to avoid impact to the Gentoo Hardened and Arch Linux communities."

[$] Reviving the Hershey fonts

Wednesday 26th of August 2015 12:16:29 AM

At the 2015 edition of TypeCon in Denver, Adobe's Frank Grießhammer presented his work reviving the famous Hershey fonts from the Mid-Century era of computing. The original fonts were tailor-made for early vector-based output devices but, although they have retained a loyal following (often as a historical curiosity), they have never before been produced as an installable digital font.

Go 1.5 released

Tuesday 25th of August 2015 09:06:07 PM
Version 1.5 of the Go language has been released. "This release includes significant changes to the implementation. The compiler tool chain was translated from C to Go, removing the last vestiges of C code from the Go code base. The garbage collector was completely redesigned, yielding a dramatic reduction [PDF] in garbage collection pause times. Related improvements to the scheduler allowed us to change the default GOMAXPROCS value (the number of concurrently executing goroutines) from 1 to the number of available CPUs. Changes to the linker enable distributing Go packages as shared libraries to link into Go programs, and building Go packages into archives or shared libraries that may be linked into or loaded by C programs (design doc)."

Happy 24th birthday, Linux kernel (Opensource.com)

Tuesday 25th of August 2015 07:58:03 PM
Opensource.com wishes Linux a happy 24th birthday, with a brief timeline of Linux history. "There's some debate in the Linux community as to whether we should be celebrating Linux's birthday today or on October 5 when the first public release was made, but Linus says he is O.K. with you celebrating either one, or both! So as we say happy birthday, let's take a quick look back at the years that have passed and how far we have come."

Ubuntu on the Mainframe: Interview with Canonical's Dustin Kirkland (Linux.com)

Monday 24th of August 2015 10:26:16 PM
Linux.com has an interview with Dustin Kirkland of Canonical's Ubuntu Product and Strategy team, about Ubuntu on the mainframe and more. "Canonical is doing a lot of different things in the enterprise space, to solve different problems. One of the interesting works going on at Canonical is Fan networking. We all know that the world is running out of IPv4 addresses (or already has). The obvious solution to this problem is IPv6, but it’s not universally available. Kirkland said, "There are still places where IPv6 doesn't exist -- little places like Amazon web services where you end up finding lots of containers." The problem multiplies as many instances in cloud need IP addresses. "Each of those instances can run hundreds of containers, each of those containers then needs to be addressable," said Kirkland."
