Major Bug in glibc Could Result in System Compromise

Google's Security team has reported a problem with the popular glibc library found in most Linux systems that could result in a serious security breach. The problem affects glibc version 2.9 and later. Specifically, the glibc client-side DNS resolver is vulnerable to a buffer overflow attack that could cause the system to access an attacker-controlled website or DNS server.

The post in the Google security blog reports that the glibc team was first alerted to the bug in July 2015 and that Red Hat has also been working on a fix for this problem. The best remedy is to update your systems and install the patch for CVE-2015-7547 as soon as possible.

If you are not immediately able to patch glibc, Google recommends you "… limit the response (i.e., via DNSMasq or similar programs) sizes accepted by the DNS resolver locally as well as ensure that DNS queries are sent only to DNS servers that limit the response size for UDP responses with the truncation bit set."

Wesnoth's Strange Legacy

I usually avoid massively multiplayer online role-playing games (MMORPGs). Instead, when I want more than solitaire or backgammon, I sometimes turn to The Battle for Wesnoth single-player campaigns, most of which can be finished in under an hour, giving me a convenient point at which to quit and do something else. However, that usually reliable strategy led me astray soon after Christmas 2015 when I discovered the Strange Legacy scenario.

Miguel de Icaza and His Ostracization from FOSS

Just before I settled down to write today, I read that Microsoft had acquired Xamarin, the company founded by Miguel de Icaza and Nat Friedman. To many, the news is the logical end to a story that has been unfolding for years now, and if the first cries of, "Traitors!" have not appeared on blogs and articles, then I expect they are only a matter of time.

Is free software too good?

I never thought I'd say this, but maybe free software and hardware would be more widely adopted if their standards were lower.
