Description

Updated xymon packages fix security vulnerabilities:


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-2016-2054).

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-2016-2055).

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-2016-2056).

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-2016-2057).

Incorrect escaping of user-supplied input in status webpages can be used to
trigger reflected cross-site scripting attacks (CVE-2016-2058).

Note that to effectively fix CVE-2016-2055, the /etc/xymon/xymonpasswd
configuration file should be owned by user and group apache with 640
permissions.
