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.");
