    mountall vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    
    Summary:
    
    mountall could mount certain filesystems with the wrong permissions.
    
    Software Description:
    - mountall: filesystem mounting tool
    
    Details:
    
    Saurav Sengupta discovered that mountall incorrectly handled umask when
    calling the mount utility, resulting in certain filesystems possibly being
    mounted with incorrect permissions.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      mountall                        2.54ubuntu0.14.10.1
    
    After a standard system update you need to reboot your computer to make
    all the necessary changes.
