  • AOSA-2017-0044: Update SystemdJUNE 29, 2017

    Please update your systemd package to version 2.3.3-4.

    A security vulnerability was recently discovered in systemd-resolved (DNS resolve configuration daemon) that…

    Certain sizes passed to dns_packet_new can cause it to allocate a buffer that’s too small. A page-aligned number - sizeof(DnsPacket) + sizeof(iphdr) + sizeof(udphdr) will do this - so, on x86 this will be a page-aligned number - 80. Eg, calling dns_packet_new with a size of 4016 on x86 will result in an allocation of 4096 bytes, but 108 bytes of this are for the DnsPacket struct.

    A malicious DNS server can exploit this by responding with a specially crafted TCP payload to trick systemd-resolved in to allocating a buffer that’s too small, and subsequently write arbitrary data beyond the end of it.

    This security vulnerability was assigned CVE-2017-9445.

  • AOSA-2017-0043: Update Linux KernelJUNE 29, 2017

    Please update your linux+kernel package so that your Linux Kernel version is 4.11.5 or higher; or update your linux+kernel+lts package so that your Linux Kernel on Long-Term Support branch is version 4.9.32 or higher.

    A security vulnerability was reported recently that…

    Until recently, /dev/snd/timer driver was prone to a data race, which led to uninitialized memory from the kernel heap being copied to the userspace.

    And this was assigned CVE-2017-10000380.

  • AOSCC 2017 Now Up for Sign Up!JUNE 14, 2017

    After several months of hard work by our community members, we have finally settled on a venue and a date for this year’s AOSCC, so…

    Welcome to our 4th annual community gathering in Guangzhou, from July 14th to 16th!

    AOSCC 2017’s venue is generously sponsored by the Guangdong University of Technology on their campus location at the H.E.M.C. (Higher Education Mega Center; 大学城). The gathering will take place in Experiment Building 4, Room 304(实验四号楼 304 实验室), here are some maps to the location…

    • Google Maps
    • Gaode Maps

    While we are still preparing for other documentations and details for the event, here’s the information we are able to produce so far…

    Already made up your mind? Just sign up here! There’s no need to provide your full name (though recommended) - it is required for all participants to sign up here so we could keep track on the amount of people coming, as this could be limited due to our venue.

    We could say at present that we could hold 50 at our venue, but this could go up if it ended up going above this amount.

    Again, please sign up here.

  • Core 4.2.2: Fin.JUNE 7, 2017

    With the release of Core 4.2.2, we have reached the end of the “Series 4” of AOSC OS Core.

    This point release updated Linux API Headers to version 4.11.3 in order to retain compatibility of the new Chromium/Google Chrome 59 browser - which contains a great deal of security updates/fixes. With July closing in, we are getting ready to unveil the collection of features and updates coming in Core “E” - our fifth Core release series - coming this summer.

    With the hint “E” - yes, we are about to start a call-for-codename for this new series of AOSC OS Core releases, we will vote for the next codename on the first day of AOSCC 2017 - details coming in the following week or so.

    Just a short announcement to tell you what’s up with the new version - and moreover, to thank you for using AOSC OS and staying supportive of our development effort.

    Core 4.2.2 is now available for amd64 users, this update will come for armel (ARMv7) and arm64 (ARMv8, AArch64) users in the coming week.

    For mipsel (MIPS-II), mips64el (MIPS64r2), powerpc (PowerPC 32-bit), ppc64 (PowerPC 64-bit, big endian) users however… Please don’t wait around, as none of these architectures will support the Chromium browser family, we have elected to skip this release. Core “E” will come in time, however, so look out for that!

    Lastly, as we have no PowerPC device available for development at the moment, we have decided to suspend all updates - and that includes security updates - for both PowerPC architectures.

    We do apologise for the inconvenience and we would further recommend that you move away from AOSC OS for this summer, in our hope to keep you safe from cyberattacks and existing bugs.

  • AOSA-2017-0039: Update SudoMAY 31, 2017

    Please update your sudo package to version 1.8.20p1.

    A recently released version of Sudo has addressed a security vulnerability titled “Potential overwrite of arbitrary files on Linux”:

    “On Linux systems, sudo parses the /proc/[pid]/stat file to determine the device number of the process’s tty (field 7). The fields in the file are space-delimited, but it is possible for the command name (field 2) to include spaces, which sudo does not account for. A user with sudo privileges can cause sudo to use a device number of the user’s choosing by creating a symbolic link from the sudo binary to a name that contains a space, followed by a number.”

    This vulnerability has been assigned CVE-2017-100036.
