    linux-ec2 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-ec2: Linux kernel for EC2
    
    Details:
    
    Matthew Daley reported an information leak in the floppy disk driver of the
    Linux kernel. An unprivileged local user could exploit this flaw to obtain
    potentially sensitive information from kernel memory. (CVE-2014-1738)
    
    Matthew Daley reported a flaw in the handling of ioctl commands by the
    floppy disk driver in the Linux kernel. An unprivileged local user could
    exploit this flaw to gain administrative privileges if the floppy disk
    module is loaded. (CVE-2014-1737)
    
    A flaw was discovered in the Reliable Datagram Sockets (RDS) protocol
    implementation in the Linux kernel for systems that lack RDS transports. An
    unprivileged local user could exploit this flaw to cause a denial of
    service (system crash). (CVE-2013-7339)
    
    An error was discovered in the Reliable Datagram Sockets (RDS) protocol
    stack in the Linux kernel. A local user could exploit this flaw to cause a
    denial of service (system crash) or possibly have unspecified other impact.
    (CVE-2014-2678)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.04 LTS:
      linux-image-2.6.32-364-ec2      2.6.32-364.77
    
    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.
