    Ubuntu Security Notice USN-1558-1
    September 07, 2012
    
    linux-ti-omap4 vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 11.10
    
    Summary:
    
    The system could be made to crash under certain conditions.
    
    Software Description:
    - linux-ti-omap4: Linux kernel for OMAP4
    
    Details:
    
    A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
    protocol implementation. A local, unprivileged user could use this flaw to
    cause a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 11.10:
      linux-image-3.0.0-1215-omap4    3.0.0-1215.27
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
    
    ATTENTION: Due to an unavoidable ABI change the kernel updates have
    been given a new version number, which requires you to recompile and
    reinstall all third party kernel modules you might have installed. If
    you use linux-restricted-modules, you have to update that package as
    well to get modules which work with the new kernel version. Unless you
    manually uninstalled the standard kernel metapackages (e.g. linux-generic,
    linux-server, linux-powerpc), a standard system upgrade will automatically
    perform this as well.
