Most networks use the IPv4 networking protocol; IPv6 is slowly being deployed to provide a larger number of available network addresses, improved security, and other features.
In an e-mail, Kettle explained that the bug isn't likely to put home users at risk because few of them will be using IPv6 networks.
"In the case of office environments, the bug is more serious since it's more likely IPv6 will be supported on the local network," said Kettle. "One can easily imagine a single user crashing much (if not nearly all) employees' machines at, let's say, Apple Inc."
The bug is also an issue for Mac OS X Server, as more servers provide native IPv6. A single user, Kettle said, could significantly affect server reliability.
The bug resides in the open source KAME Project's IPv6 implementation, which may not properly process IPv6 packets that contain an IP payload compression protocol (IPComp) header. Mac OS X is built atop BSD Unix, which contains KAME Project code.
Kettle observes that the bug was identified in November and that Apple has not acknowledged that Mac OS X is vulnerable. The "very existence of this bug is quite indicative of Apple's patching and security practices," he said.
2014 Next-Gen WAN SurveyWhile 68% say demand for WAN bandwidth will increase, just 15% are in the process of bringing new services or more capacity online now. For 26%, cost is the problem. Enter vendors from Aryaka to Cisco to Pertino, all looking to use cloud to transform how IT delivers wide-area connectivity.
The UC Infrastructure TrapWorries about subpar networks tanking unified communications programs could be valid: Thirty-one percent of respondents have rolled capabilities out to less than 10% of users vs. 21% delivering UC to 76% or more. Is low uptake a result of strained infrastructures delivering poor performance?
