![]() cpe:2.3:o:freebsd_foundation:freebsd:13.A remote attacker with control over the Wi-Fi hotspot can send specially beacon crafted frames to the FreeBSD Wi-Fi client in scanning mode, trigger a heap-based buffer overflow and execute arbitrary code on the system. The vulnerability exists due to a boundary error within the 802.11 beacon handling routine in FreeBSD Wi-Fi client. The vulnerability allows a remote attacker to execute arbitrary code on the target system. Is there known malware, which exploits this vulnerability?ĬWE-ID: CWE-122 - Heap-based Buffer Overflow cpe:2.3:o:freebsd_foundation:freebsd:13.1:*:*:*:*:*:*:*Ĭan this vulnerability be exploited remotely?.The vulnerability can be used to escape jail environment. A local user can trigger a race condition, which can lead to memory corruption and code execution. The total size of the user-provided nmreq to nmreq_copyin() function was first computed and then trusted during the copyin operation. The vulnerability exists due to a race condition in netmap. The vulnerability allows a local user to bypass implemented security restrictions. Caraballo-Vega, NASA Goddard Space Flight John E.1) Time-of-check Time-of-use (TOCTOU) Race ConditionĬWE-ID: CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition The final result will be a reference architecture with representative hardware and software that will enable the NCCS to build, deploy, and efficiently maintain extremely cost-effective 100-Gbps firewalls. In addition to hardware improvements, updates to the network capabilities in the FreeBSD-Current version will be closely monitored and applied as appropriate. What's Nextįurther tests will continue verifying the above results with even more capable systems-such as 40-gigabit and 100-gigabit Ethernet cards-to achieve even higher performance. The development and deployment of these tools will enable scientists to efficiently and securely push their research further without having to overcome potentially huge obstacles from the lack of high-speed packet filtering. The ability to deploy security services (e.g., firewalls) without affecting performance opens the possibility of deploying more capable systems for science without compromising security. Why HPC MattersĪs the demand for more compute and data resources increase, high-performance computing (HPC) environments like the NCCS will always require higher-speed security tools and networks. The tests have shown that at the optimally tuned and configured FreeBSD system, it is possible to create a system that can manage the huge amounts of pps needed to create a 100-Gbps firewall with commodity components. Netmap-fwd increased the pps rate significantly.The choice of network card can have a significant impact on pps, tuning, and netmap support.netmap supports access to network cards (NICs), host stack, virtual ports (the 'VALE' switch), and 'netmap pipes'. Together with its companion VALE software switch, it is implemented as a single kernel module and available for FreeBSD, Linux and now also Windows (OSX still missing, unfortunately). FreeBSD was able to send more pps as a client than Centos 6. 'autoPlay':false '> netmap is a framework for high speed packet I/O.We established a pps baseline using FreeBSD-10.3 and discovered several interesting features of the packet-filtering environment: The testing has shown that the pps will rise as newer versions of the operating systems are deployed. Additional testing has involved enabling the Common Address Redundancy Protocol (CARP) to achieve an active/active architecture. We used the tools iperf3, nuttcp, and netperf to monitor the performance of the maximum bandwidth through the cards. Building on this work, we are comparing FreeBSD-11.0 and FreeBSD-Current along with implementing the netmap-fwd Application Programming Interface (API) and tuning the 10-gigabit Ethernet cards. ![]() Previous NCCS work testing the FreeBSD operating system for high-performance routing reached a maximum of 4 million pps. The test domain consists of several existing systems within the NCCS, including switches (Dell S4084), routers (Dell R530s), servers (Dell R420s, and C6100s), and host card adapters (10-Gbps Mellanox ConnectX2 and Intel 8259 x Ethernet cards). ![]() The aim of this project is to create a commodity-based platform that can process enough packets per second (pps) to sustain a 100-Gbps workload within the NCCS computational environment. In order to support the requirements of emerging services, including the Advanced Data Analytics Platform (ADAPT) private cloud, the NCCS security team has proposed an architecture to provide extremely cost-effective 100-gigabit-per-second (Gbps) firewalls. The continuous growth of the NASA Center for Climate Simulation (NCCS) requires providing high-performance security tools and enhancing the network capacity.
