========================================================================== Ubuntu Security Notice USN-2484-1 January 26, 2015
unbound vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10 - Ubuntu 14.04 LTS
Summary:
Unbound could be made to consume resources if it received specially crafted network traffic.
Software Description: - unbound: validating, recursive, caching DNS resolver
Details:
Florian Maury discovered that Unbound incorrectly handled delegation. A remote attacker could possibly use this issue to cause Unbound to consume resources, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.10: libunbound2 1.4.22-1ubuntu4.14.10.1 unbound 1.4.22-1ubuntu4.14.10.1
Ubuntu 14.04 LTS: libunbound2 1.4.22-1ubuntu4.14.04.1 unbound 1.4.22-1ubuntu4.14.04.1
In general, a standard system update will make all the necessary changes.
