A Floating Point Unit (FPU) state information leakage flaw was found in the way the Linux kernel saved and restored the FPU state during task switch Linux kernels that follow the "Lazy FPU Restore" scheme are vulnerable to the FPU state information leakage issue An unprivileged local attacker could use this flaw to read FPU state bits by conducti ...

Description of Problem An issue has been identified in certain CPUs that may allow code running in a guest VM to read data from another process in the same VM or another VM running on the same host  The data that can be read is limited to specific CPU registers rather than memory or disk storage; however, those registers may contain sensitive ...

Also, make sure you update your Juniper kit quickly

Roundup This week, when we weren't watching the football and sobbing uncontrollably, we saw security headaches at NPM and Ticketmaster, and a priest in hot water with cybercrime charges. But there's always more in the security world. Here are a few other bits of security news from recent days. The US Senate is asking the Justice Department to look into the possibility that an Islamic extremist hacking group was actually the work of the Russian government. Senators Ron Wyden (D-OR) and Cory Gardn...
