DESCRIPTION:
A vulnerability has been discovered in NetSupport Manager, which can
be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to an error within the NetSupport
Manager client when handling certain packets, which can be exploited
to cause a stack-based buffer overflow by e.g. sending specially
crafted packets to the client (port 5405/TCP).
The vulnerability is confirmed in NetSupport Manager client for Linux
version 11 and is also reported in NetSupport Manager client for Linux
version 10.50.0, NetSupport Manager client for Solaris version 9.50,
and NetSupport Manager client for Mac OS X version 11.00. Other
versions may also be affected.
Note: Reportedly, the Windows version is not affected.
SOLUTION:
Restrict network access using a firewall.
