[SECURITY] [DLA 488-1] xymon security update



-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

Package        : xymon
Version        : 4.3.0~beta2.dfsg-9.1+deb7u1
CVE ID         : CVE-2016-2054 CVE-2016-2055 CVE-2016-2056 CVE-2016-2058


Markus Krell discovered that Xymon (formerly known as Hobbit), 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-2016-2058

  Incorrect escaping of user-supplied input in status webpages can
  be used to trigger reflected cross-site scripting attacks.


For Debian 7 "Wheezy", these problems have been fixed in version
4.3.0~beta2.dfsg-9.1+deb7u1.

We recommend that you upgrade your xymon packages.
