DESCRIPTION:
A vulnerability has been reported in NX Web Companion, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the applet insecurely handling
updates, which leads to insufficient authenticity validation of
downloaded update files. This can be exploited to download and
execute arbitrary files by tricking a user into visiting a malicious
web site.

Successful exploitation requires that the user approves an update on
an untrusted website.

The vulnerability is reported in version 3.5.0-3. Other versions may
also be affected.

SOLUTION:
Do not update on an untrusted website.
