Updated Xen kernels for XS plans have been released that address a recent security issue for Linux >= 2.6.30. (RDS protocol exploit)
This only effects XS plans running either 2.6.31.6 or 2.6.35.4.
If you are running PV-Grub, you should update your kernel via your distributions package manager.
Simply reboot your VPS to update your kernel to the recent version.
Be sure to download the updated kernel modules pack if you have them installed:
cd /lib/modules
mv 2.6.31.6 2.6.31.6.old
wget http://www.quantact.com/dl/domU-2.6.31.6-modules.tgz
tar -xzf domU-2.6.31.6-modules.tgz
or
cd /lib/modules
mv 2.6.35.4 2.6.35.4.old
wget http://www.quantact.com/dl/domU-2.6.35.4-modules.tgz
tar -xzf domU-2.6.35.4-modules.tgz
Until you are able to reboot, a workaround is to run the following as root:
echo “alias net-pf-21 off” > /etc/modprobe.d/disable-rds
This will disable loading of the RDS module for non root users.
