    sosreport vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 15.10
    - Ubuntu 15.04
    - Ubuntu 14.04 LTS
    
    Summary:
    
    sosreport could be made to expose sensitive information or overwrite files
    as the administrator.
    
    Software Description:
    - sosreport: Set of tools to gather troubleshooting data from a system
    
    Details:
    
    Dolev Farhi discovered an information disclosure issue in SoS. If the
    /etc/fstab file contained passwords, the passwords were included in the
    SoS report. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-3925)
    
    Mateusz Guzik discovered that SoS incorrectly handled temporary files. A
    local attacker could possibly use this issue to overwrite arbitrary files
    or gain access to temporary file contents containing sensitive system
    information. (CVE-2015-7529)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 15.10:
      sosreport                       3.2-2ubuntu1.1
    
    Ubuntu 15.04:
      sosreport                       3.2-2ubuntu0.1
    
    Ubuntu 14.04 LTS:
      sosreport                       3.1-1ubuntu2.2
    
    In general, a standard system update will make all the necessary changes.
