    Ubuntu Security Notice USN-2529-1
    March 12, 2015
    
    linux-lts-utopic vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.04 LTS
    
    Summary:
    
    The system could be made to crash or run programs as an administrator.
    
    Software Description:
    - linux-lts-utopic: Linux hardware enablement kernel from Utopic
    
    Details:
    
    It was discovered that the Linux kernel's Infiniband subsystem did not
    properly sanitize its input parameters while registering memory regions
    from userspace. A local user could exploit this flaw to cause a denial of
    service (system crash) or to potentially gain administrative privileges.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.04 LTS:
      linux-image-3.16.0-31-generic   3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-generic-lpae  3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-lowlatency  3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-powerpc-e500mc  3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-powerpc-smp  3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-powerpc64-emb  3.16.0-31.43~14.04.1
      linux-image-3.16.0-31-powerpc64-smp  3.16.0-31.43~14.04.1
