    linux-mvl-dove vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 10.10
    
    Summary:
    
    Several security issues were fixed in the kernel.
    
    Software Description:
    - linux-mvl-dove: Linux kernel for DOVE
    
    Details:
    
    Clement Lecigne discovered a bug in the HFS filesystem. A local attacker
    could exploit this to cause a kernel oops. (CVE-2011-2203)
    
    A flaw was found in how the Linux kernel handles user-defined key types. An
    unprivileged local user could exploit this to crash the system.
    (CVE-2011-4110)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 10.10:
      linux-image-2.6.32-422-dove     2.6.32-422.40
    
    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.
