- Slackware updates
- Slackware has been silent for some time (noted in this comment thread). Although we haven't seen any advisories in the LWN mailbox, the changelogs are showing some new updates. Slackware users should update their systems.
- Stable kernels 3.0.19, 3.2.3 and 2.6.32.56
- Friday's security updates
-
CentOS has updated ghostscript (C6; C5; C4: multiple vulnerabilities), php (C6; C5; C4: remote code execution), and C5: php53 (remote code execution).
Debian has updated iceweasel (multiple vulnerabilities), iceape (multiple vulnerabilities), and php5 (remote code execution).
Mandriva has updated mozilla (multiple vulnerabilities).

CentOS has updated ghostscript (C6; C5; C4: multiple vulnerabilities), php (C6; C5; C4: remote code execution), and C5: php53 (remote code execution).
- PHP 5.3.10 released with critical security fix
- The PHP 5.3.10 release is out; it contains a fix for a remote code execution bug introduced recently by another security fix. Anybody running 5.3.9 should probably upgrade as soon as possible.
- Critical PHP vulnerability being fixed (The H)
- The H is reporting that a critical remote code execution bug has been found in PHP that was caused by the recent fix for the widespread denial of service via hash collisions vulnerability. "The cause of the problem is the security update to PHP 5.3.9, which was written to prevent denial of service (DoS) attacks using hash collisions. To do so, the developers limited the maximum possible number of input parameters to 1,000 in php_variables.c using max_input_vars. Because of mistakes in the implementation, hackers can intentionally exceed this limit and inject and execute code. The bug is considered to be critical as code can be remotely injected over the web."
- Security advisories for Thursday

- Seigo: Spark answers
- Aaron Seigo answers questions about the Spark tablet, which is based on Plasma Active, that he announced on January 29. There is more information about the hardware and software, delivery timeframe (May 2012), and pre-orders: "Pre-order registration will open early next week. This was one piece in the puzzle that was taking a bit [longer] than I hoped for to come together, but it's finally slotted in and our distribution partner has got the necessary infrastructure settled. I'll lift the veil off of the pre-order and our distribution strategy when it goes live."
- Gettys: Bufferbloat demonstration videos
- Jim Gettys says: "If people have heard of bufferbloat at all, it is usually just an abstraction despite having personal experience with it. Bufferbloat can occur in your operating system, your home router, your broadband gear, wireless, and almost anywhere in the Internet. They still think that if experience poor Internet speed means they must need more bandwidth, and take vast speed variation for granted. Sometimes, adding bandwidth can actually hurt rather than help. Most people have no idea what they can do about bufferbloat. So I’ve been working to put together several demos to help make bufferbloat concrete, and demonstrate at least partial mitigation." Definitely useful viewing for anybody who is concerned with the problem and how to begin addressing it.

- Kuhn: Some Thoughts on Conservancy's GPL Enforcement
- Bradley Kuhn has posted a lengthy explanation of the Software Freedom Conservancy's GPL enforcement activities and the demands they make. "I started using this request regularly around 2002 because violators express a concern that, if they came into compliance due to my efforts, what was to stop others from coming to complain, in sequence, and wasting their time? I suggested that if they came into compliance all at once, on all FLOSS licenses involved, it would be easy for me to be on their side, should someone else complain. Namely, I'd come to their defense and say: 'Yes, they were out of compliance, but we've checked everything and they're now in compliance throughout this product. Those who are now complaining are being unfair, since — while this violator had trouble initially — their compliance with all FLOSS licenses is now adequate'."
- The Document Foundation will be based in Berlin
- The Document Foundation has announced that its long-awaited legal entity will be based in Berlin. "'After many months of work in close cooperation with the authorities, we were able to keep the spirit of the community bylaws, and incorporate them into legally binding statutes, that ensure the promises that TDF has made in its manifesto', says Michael (Mike) Schinagl, a Berlin-based lawyer and contributor to various free software projects, who has been driving the legal aspects of the foundation set-up from the very beginning."

Ubuntu has updated usbmuxd (code execution via hostile USB device).

- [$] A tempest in a toybox
- The eLinux.org web site is currently promoting a project to write a replacement for Busybox under a permissive license. Normally, the writing of more free software is seen as a good thing, but, in this case, there have been complaints about the perceived motivation behind the project. What this discussion shows is that there are some divisions within our community on how our licenses should be enforced - and even what those licenses say.
- Apache HTTP Server 2.2.22 released
- Version 2.2.22 of the Apache web server is out. The main point of this release appears to be the fixing of six different CVE numbers, so people with their own Apache builds probably want to grab the update.

- Syntax coloring utility
- I often write HTML pages or documentation that includes code samples. When the code is presented this way, it's much easier to follow if it features syntax highlighting. I had found a script that could highlight Perl code, and then I realized I needed the same thing for C code as well. I've posted a new script on my web site that inserts HTML markup into source code files to provide colored syntax highlighting.

The response takes into account the clarification of the initiative,
through the QA session, yet the response is also equally applicable advice
to any organisation wishing to have applications written that run across
a very diverse range of devices and platforms without having to develop
and maintain multiple versions of the exact same software.

- Implementing spam protection in Wiki engines
- Spam is really a problem in many Wiki communities, often forcing at
least temporary to restrict editing rights. Most of the recent attempts
to find a solution focus around captchas and spam lists. Captchas may be
efficient to some extent; the problem is that to make them unreadable
for bots, they must be twisted enough to become also difficult for
humans to read. Lists seem less and less efficient, often accumulating
thousands
of entries and still leaving enough gaps for spammers. Spammers
frequently use the Wiki search box to check if there is already some
spam on the site - this shows that Wiki may be purely maintained and
they can add more. Hence it may make sense to implement the delayed
indexing but it also delays indexing of legitimate content. Blocking IP
addresses is also no longer useful due DHCP.
One of the solutions may be to use combined protection rather than relying on some single "killer" approach. The rationale is to make spammer to invest more and more work into building the spam bot. Requiring a complex bot does not make the attack impossible but may statistically eliminate significant percent of spammers that are not willing to invest enough resources.

- Piracy and Free Software
- Over the last few years, many advocates of access to information have gathered and organized under the banner of piracy. Should FLOSS and free culture advocates embrace advocates of piracy as comrades in arms or condemn them? Must we choose between being either with the pirates or against them? I believe that, unintuitively, if we take a strong principled position in favor of information freedom and distinguish between principles and tactics, a more nuanced "middle ground" response to piracy is possible. On free culture and free software's terms, we can suggest that piracy is not ethically wrong, but that it is an shortsighted and unwise way to try to promote sharing that we should not support.
