LXC 1.1.3 release announcement

Aug 14, 2015
This is the third bugfix release for LXC 1.1.



  • Security fix for CVE-2015-1331
  • Security fix for CVE-2015-1334
  • Fix an ABI regression in LXC 1.1 compared to LXC 1.0.
    Fixing this unfortunately means that binaries built against LXC
    1.1.0, 1.1.1 and 1.1.2 will need rebuilding against LXC 1.1.3.
    This is however preferable to not having backward compatibility with
    binaries built for LXC 1.0 and its bugfix releases.
