VU#507496: GIGABYTE BRIX UEFI firmware fails to implement write protection and is not cryptographically signed

GIGABYTE BRIX UEFI firmware for the GB-BSi7H-6500 and GB-BXi7-5775 platforms,versions vF6 and vF2 respectively,fails to properly set the BIOSWE,BLE,SMM_BWP,and PRx bits to enforce write protection. It also is not cryptographically signed. These issues may permit an attacker to write arbitrary code to the platform firmware,potentially allowing for persistent firmware level rootkits or the creation of a permanent denial of service condition in the platform.

VU#600671: PCAUSA Rawether for Windows local privilege escalation

PCAUSA’s Rawether framework does not properly validate BPF data,allowing a crafted malicious BPF program to perform operations on memory outside of its typical bounds on the driver’s receipt of network packets. This vulnerability may be exploited to perform local privilege escalation on Windows systems. Continue reading VU#600671: PCAUSA Rawether for Windows local privilege escalation
