USN-1456-1: Nut vulnerability
31 May 2012
Nut could be made to crash if it received specially crafted network traffic.
Releases
Packages
- nut - Network UPS tools
Details
Sebastian Pohle discovered that Nut did not properly validate its input
when receiving data over the network. If upsd was configured to allow
connections over the network, a remote attacker could exploit this to
cause a denial of service (application crash).
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 11.04
Ubuntu 10.04
In general, a standard system update will make all the necessary changes.
