FreeBSD Local Root Escalation Vulnerability

Filed under

BSD

It’s been a long time since we’ve heard about a problem with FreeBSD, partially because the mass of people using it isn’t that large and secondly because BSD tends to be pretty secure as operating systems go.

It’s a pretty serious flaw this time with root escalation, thankfully it’s only a local exploit though and not remotely exploitable.

Although a user could get user access on the system through an exploit in a web facing application, and use some kind of PHP/Python web shell to exploit and get root.

Unfortunately, in many cases, ecosystem development presents a "chicken and egg" problem: Developers won't build apps until you have users, and users won't select your product until you have apps.

Linux 4.2 Offers Performance Improvements For Non-Transparent Bridging

The Non-Transparent Bridge code is undergoing a big rework that has "already produced some significant performance improvements", according to its code maintainer Jon Mason. For those unfamiliar with NTB, it's described by the in-kernel documentation, "NTB (Non-Transparent Bridge) is a type of PCI-Express bridge chip that connects the separate memory systems of two computers to the same PCI-Express fabric. Existing NTB hardware supports a common feature set, including scratchpad registers, doorbell registers, and memory translation windows." Or explained simply by the Intel Xeon documentation that received the NTB support, "Non-Transparent Bridge (NTB) enables high speed connectivity between one Intel Xeon Processor-based platform to another (or other IA or non-IA platform via the PCIe interface)."
