VPNs at risk from security glitch

Security

A flaw in a key Internet security protocol used by major networking products could open systems up to denial-of-service (DoS) and other kinds of attacks, experts have warned.

Finnish researchers at the University of Oulu announced Monday that they have found a vulnerability in the Internet Security Association and Key Management Protocol, or ISAKMP. The technology is used in IPsec virtual private network and firewall products from a range of networking companies, including giants Cisco and Juniper.

"These flaws may expose DoS conditions, format string vulnerabilities, and buffer overflows," the advisory said. All these could shut down devices and slow transmission of data across the Internet. In some cases, they could also allow hackers to execute code and hijack a device, NISCC warned.

Intel Beignet Is Working Out Surprisingly Well For OpenCL On Linux

Beignet is the project out of Intel's Open-Source Technology Center for exposing GPGPU/compute capabilities out of Ivy Bridge hardware and newer when using a fully open-source Linux stack. While Beignet differs greatly from Gallium3D's Clover state tracker, this Intel-specific open-source OpenCL implementation is working out quite well for Ubuntu Linux. While I've been writing about Intel's Beignet project since early 2013, it's probably been about a year now since I tried out the code, which is developed by Intel's OTC graphics team in China. This weekend I tried out Beignet v0.9.2 as trying out the newest Intel OpenCL code has been on my TODO list for a while and it's been working out rather well in my initial tests. Read more
