    Ubuntu Security Notice USN-1585-1
    September 26, 2012
    
    freeradius vulnerability
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 11.04
    
    Summary:
    
    FreeRADIUS could be made to crash or run programs if it received
    specially crafted network traffic.
    
    Software Description:
    - freeradius: a high-performance and highly configurable RADIUS server
    
    Details:
    
    Timo Warns discovered that FreeRADIUS incorrectly handled certain long
    timestamps in client certificates. A remote attacker could exploit this
    flaw and cause the FreeRADIUS server to crash, resulting in a denial of
    service, or possibly execute arbitrary code.
    
    The default compiler options for affected releases should reduce the
    vulnerability to a denial of service.
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      freeradius                      2.1.10+dfsg-3ubuntu0.12.04.1
    
    Ubuntu 11.10:
      freeradius                      2.1.10+dfsg-3ubuntu0.11.10.1
    
    Ubuntu 11.04:
      freeradius                      2.1.10+dfsg-2ubuntu2.1
    
    In general, a standard system update will make all the necessary changes.
