    rsync vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 17.10
    - Ubuntu 17.04
    - Ubuntu 16.04 LTS
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in rsync.
    
    Software Description:
    - rsync: fast, versatile, remote (and local) file-copying tool
    
    Details:
    
    It was discovered that rsync proceeds with certain file metadata
    updates before checking for a filename. An attacker could use this to
    bypass access restrictions. (CVE-2017-17433)
    
    It was discovered that rsync does not check for fnamecmp filenames and
    also does not apply the sanitize_paths protection mechanism to
    pathnames. An attacker could use this to bypass access restrictions.
    (CVE-2017-17434)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 17.10:
      rsync                           3.1.2-2ubuntu0.1
    
    Ubuntu 17.04:
      rsync                           3.1.2-1ubuntu0.1
    
    Ubuntu 16.04 LTS:
      rsync                           3.1.1-3ubuntu1.1
    
    Ubuntu 14.04 LTS:
      rsync                           3.1.0-2ubuntu0.3
    
    In general, a standard system update will make all the necessary
    changes.
