Debian DLA-488-1 : xymon security update
High Nessus Plugin ID 91324
SynopsisThe remote Debian host is missing a security update.
DescriptionMarkus Krell discovered that Xymon (formerly known as Hobbit), a network- and applications-monitoring system, was vulnerable to the following security issues :
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.
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.
The commands handling password management do not properly validate user-supplied input, and are thus vulnerable to shell command injection by a remote user.
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.
