    linux vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 8.04 LTS
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux: Linux kernel
    
    Details:
    
    Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
    interface. A local attacker on non-x86 systems might be able to cause a
    denial of service. (CVE-2011-1476)
    
    Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)
    driver for Yamaha FM synthesizer chips. A local user can exploit this to
    cause memory corruption, causing a denial of service or privilege
    escalation. (CVE-2011-1477)
    
    Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
    partitions. A local user could exploit this to cause a denial of service or
    escalate privileges. (CVE-2011-2182)
    
    A flaw was discovered in the Linux kernel's NFSv4 (Network File System
    version 4) file system. A local, unprivileged user could use this flaw to
    cause a denial of service by creating a file in a NFSv4 filesystem.
    (CVE-2011-4324)
    
    A flaw was found in how the linux kernel handles user-space held futexs. An
    unprivileged user could exploit this flaw to cause a denial of service or
    possibly elevate privileges. (CVE-2012-0028)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 8.04 LTS:
      linux-image-2.6.24-31-386       2.6.24-31.99
      linux-image-2.6.24-31-generic   2.6.24-31.99
      linux-image-2.6.24-31-hppa32    2.6.24-31.99

      linux-image-2.6.24-31-itanium   2.6.24-31.99
      linux-image-2.6.24-31-lpia      2.6.24-31.99
      linux-image-2.6.24-31-lpiacompat  2.6.24-31.99
      linux-image-2.6.24-31-mckinley  2.6.24-31.99
      linux-image-2.6.24-31-openvz    2.6.24-31.99
      linux-image-2.6.24-31-powerpc   2.6.24-31.99
      linux-image-2.6.24-31-powerpc-smp  2.6.24-31.99
      linux-image-2.6.24-31-powerpc64-smp  2.6.24-31.99
      linux-image-2.6.24-31-rt        2.6.24-31.99
      linux-image-2.6.24-31-server    2.6.24-31.99
      linux-image-2.6.24-31-sparc64   2.6.24-31.99
      linux-image-2.6.24-31-sparc64-smp  2.6.24-31.99
      linux-image-2.6.24-31-virtual   2.6.24-31.99
      linux-image-2.6.24-31-xen       2.6.24-31.99
    
    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.
