Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : nut vulnerability (USN-1456-1)
High Nessus Plugin ID 59320
SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionSebastian 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).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected nut and / or nut-server packages.
