A bite of Python (Red Hat Security Blog)

cs, 2016-09-08 18:59
On the Red Hat Security Blog, Ilya Etingof describes some traps for the unwary in Python, some that have security implications. "Being easy to pick up and progress quickly towards developing larger and more complicated applications, Python is becoming increasingly ubiquitous in computing environments. Though apparent language clarity and friendliness could lull the vigilance of software engineers and system administrators -- luring them into coding mistakes that may have serious security implications. In this article, which primarily targets people who are new to Python, a handful of security-related quirks are looked at; experienced developers may well be aware of the peculiarities that follow."

[$] What's next for Apache OpenOffice

cs, 2016-09-08 10:00
Concerns about the viability of the Apache OpenOffice (AOO) project are not new; they had been in the air for a while by the time LWN looked at the project's development activity in early 2015. Since then, though, the worries have grown more pronounced, especially after AOO's recent failure to produce a release with an important security fix nearly one year after being notified of the vulnerability. The result is an internal discussion on whether the project should be "retired," or whether it will find a way to turn its fortunes around.

[$] An asynchronous Internet in GNOME

cs, 2016-09-08 05:57

At GUADEC 2016 in Karlsruhe, Germany, Jonathan Blandford challenged the GNOME project to rethink how its desktop software uses network access. The GNOME desktop assumes Internet connectivity is always available, which has the side effect of making the software stack considerably less useful and, indeed, usable to people who live in those places regarded as the developing world.

Danko: Next steps for Gmane

k, 2016-09-06 20:01
LWN previously reported that Gmane creator and maintainer Lars Magne Ingebrigtsen shut down the website and was contemplating shutting down the service entirely. Martin Danko now reports that Gmane has a new maintainer. "I petitioned some of our directors to allow us to offer to take it over and in the end we entered into agreement with Lars to take over Gmane. The assets of Gmane have been placed into a UK company Gmane Ltd. As part of the agreement, we have received the INN spool with all the articles but none of the code that drives the site. We’ve started rebuilding parts of the site just to get it back online, its not perfect and there are pieces missing but we’re working on building all the functionality back into the site."

Kernel prepatch 4.8-rc5

h, 2016-09-05 07:56
The 4.8-rc5 kernel prepatch is available for testing. "So rc5 is noticeably bigger than rc4 was, and my hope last week that we were starting to calm down and shrink the releases seems to have been premature. [...] Not that any of this looks worrisome per se, but if things don't start calming down from now, this may be one of those releases that will need an rc8. We'll see."

Z-Wave protocol specification now public

p, 2016-09-02 23:58

The Z-Wave wireless home-automation protocol has been released to the public. In years past, the specification was only available to purchasers of the Z-Wave Alliance's development kit, forcing open-source implementations to reverse-engineer the protocol. The official press release notes that there are several such projects, including OpenZWave; Z-Wave support is also vital to higher-level Internet-of-Things abstraction systems like AllJoyn.

Suspect in kernel.org breakin arrested

p, 2016-09-02 15:08
The US Department of Justice has announced that it has arrested a suspect in the 2011 kernel.org breakin. "[Donald Ryan] Austin is charged with causing damage to four servers located in the Bay Area by installing malicious software. Specifically, he is alleged to have gained unauthorized access to the four servers by using the credentials of an individual associated with the Linux Kernel Organization. According to the indictment, Austin used that access to install rootkit and trojan software, as well as to make other changes to the servers."

Contemplating the possible retirement of Apache OpenOffice

p, 2016-09-02 08:02
Outgoing Apache OpenOffice project management committee (PMC) chair Dennis Hamilton has begun the discussion of a possible (note possible at this point) shutdown of the project. "In the case of Apache OpenOffice, needing to disclose security vulnerabilities for which there is no mitigation in an update has become a serious issue. In responses to concerns raised in June, the PMC is currently tasked by the ASF Board to account for this inability and to provide a remedy. An indicator of the seriousness of the Board's concern is the PMC been requested to report to the Board every month, starting in August, rather than quarterly, the normal case. One option for remedy that must be considered is retirement of the project. The request is for the PMC's consideration among other possible options." (Thanks to James Hogarth.)

Also of interest is this note on how the handling of CVE-2016-1513 went.

Building a new Tor that can resist next-generation state surveillance (ars technica)

cs, 2016-09-01 10:07
Here's a lengthy ars technica article on efforts to replace Tor with something more secure. "As a result, these known weaknesses have prompted academic research into how Tor could be strengthened or even replaced by some new anonymity system. The priority for most researchers has been to find better ways to prevent traffic analysis. While a new anonymity system might be equally vulnerable to adversaries running poisoned nodes, better defences against traffic analysis would make those compromised relays much less useful and significantly raise the cost of de-anonymising users."
