Four New Security Advisories Released for NetBSD

Dan writes "The NetBSD security team has issued Four NetBSD Security Advisories. (1) Format string vulnerability in zlib gzprintf(): a buffer overflow can result in arbitrary code execution. (2) RSA timing attack in OpenSSL code can enable remote recovery of private keys, from a host with low-latency access to the server - such as the local host, or a host on the LAN. (3) Encryption weakness in OpenSSL code enables an attacker to perform crypto operations using server's private keys. Finally (4), faulty length checks in xdrmem_getbytes (within libc) are susceptible to integer overflows that affect memory allocation in their local buffers."

    Why link to freebsdforums when you can get the original announcement here?

      Yeah, and you can get it a day earlier...

      time to update the system again...

      Its times like this that I wish BSD's package management system allowed one to upgrade only part of the system without getting the source or doing an upgrade.... That is one thing I do like about linux's rpm. Its easeier to upgrade IMHO.

      Oh well this way I get the latest build, who knows maybe they'll have wsmoused in it....

      Some people are already working on that in the -CURRENT tree. It's called syspkg. See the original post here

      Hmm, while you _do_ have to get the source (as if that was a bad thing!), it's certainly very simple to update only the relevant parts. As the SA states, you do not need to update the entire system but can simply do:

      # cd src

      # cvs update -d -P -r netbsd-1-6 lib/libz/gzio.c

      # cd lib/libz

      # make USETOOLS=no cleandir dependall

      # make USETOOLS=no install

      (Similarly for the other advisories.)
      This is not really very difficult.

    No, some of us run a BSD because we like UNIX, and the BSD variants are UNIX-like. Linux isn't as UNIX-like. It's been subverted by a bunch of zealots whose main focus is 'win against Microsoft' which is really irrelevant to some of us.

    Who cares? Those of us with a clue about computers run Windows. Everyone knows Windows is the best OS. You Lunix and BSD zealots just don't want to admit it.

    The End of FreeBSD

    [ed. note: in the following text, former FreeBSD developer Mike Smith gives his reasons for abandoning FreeBSD]

    When I stood for election to the FreeBSD core team nearly two years ago, many of you will recall that it was after a long series of debates during which I maintained that too much organisation, too many rules and too much formality would be a bad thing for the project.

    Today, as I read the latest discussions on the future of the FreeBSD project, I see the same problem; a few new faces and many of the old going over the same tired arguments and suggesting variations on the same worthless schemes. Frankly I'm sick of it.

    FreeBSD used to be fun. It used to be about doing things the right way. It used to be something that you could sink your teeth into when the mundane chores of programming for a living got you down. It was something cool and exciting; a way to spend your spare time on an endeavour you loved that was at the same time wholesome and worthwhile.

    It's not anymore. It's about bylaws and committees and reports and milestones, telling others what to do and doing what you're told. It's about who can rant the longest or shout the loudest or mislead the most people into a bloc in order to legitimise doing what they think is best. Individuals notwithstanding, the project as a whole has lost track of where it's going, and has instead become obsessed with process and mechanics.

    So I'm leaving core. I don't want to feel like I should be "doing something" about a project that has lost interest in having something done for it. I don't have the energy to fight what has clearly become a losing battle; I have a life to live and a job to keep, and I won't achieve any of the goals I personally consider worthwhile if I remain obligated to care for the project.

    Discussion

    I'm sure that I've offended some people already; I'm sure that by the time I'm done here, I'll have offended more. If you feel a need to play to the crowd in your replies rather than make a sincere effort to address the problems I'm discussing here, please do us the courtesy of playing your politics openly.

    From a technical perspective, the project faces a set of challenges that significantly outstrips our ability to deliver. Some of the resources that we need to address these challenges are tied up in the fruitless metadiscussions that have raged since we made the mistake of electing officers. Others have left in disgust, or been driven out by the culture of abuse and distraction that has grown up since then. More may well remain available to recruitment, but while the project is busy infighting our chances for successful outreach are sorely diminished.

    There's no simple solution to this. For the project to move forward, one or the other of the warring philosophies must win out; either the project returns to its laid-back roots and gets on with the work, or it transforms into a super-organised engineering project and executes a brilliant plan to deliver what, ultimately, we all know we want.

    Whatever path is chosen, whatever balance is struck, the choosing and the striking are the important parts. The current indecision and endless conflict are incompatible with any sort of progress.

    Trying to dissect the above is far beyond the scope of any parting shot, no matter how distended. All I can really ask of you all is to let go of the minutiae for a moment and take a look at the big picture. What is the ultimate goal here? How can we get there with as little overhead as possible? How would you like to be treated by your fellow travellers?

    Shouts

    To the Slashdot "BSD is dying" crowd - big deal. Death is part of the cycle; take a look at your soft, pallid bodies and consider that right this very moment, parts of you are dying. See? It's not so bad.

    To the bulk of the FreeBSD committerbase and the developer community at large - keep your eyes on the real goals. It'
