    Markus Krell discovered that xymon, a network- and
    applications-monitoring system, was vulnerable to the following
    security issues:
    
    CVE-2016-2054
    
      The incorrect handling of user-supplied input in the "config"
      command can trigger a stack-based buffer overflow, resulting in
      denial of service (via application crash) or remote code execution.
    
    CVE-2016-2055
    
      The incorrect handling of user-supplied input in the "config"
      command can lead to an information leak by serving sensitive
      configuration files to a remote user.
    
    CVE-2016-2056
    
      The commands handling password management do not properly validate
      user-supplied input, and are thus vulnerable to shell command
      injection by a remote user.
    
    CVE-2016-2057
    
      Incorrect permissions on an internal queuing system allow a user
      with a local account on the xymon master server to bypass all
      network-based access control lists, and thus inject messages
      directly into xymon.
    
    CVE-2016-2058
    
      Incorrect escaping of user-supplied input in status webpages can
      be used to trigger reflected cross-site scripting attacks.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 4.3.17-6+deb8u1.
    
    We recommend that you upgrade your xymon packages.
