NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Palo Alto Network’s GlobalProtect Secure Socket Layer (SSL) virtual private network contains remote code execution bug
Description: CVE-2019-1579 is a remote code execution vulnerability in Palo Alto Network’s GlobalProtect Secure Socket Layer (SSL) virtual private network (VPN). At the time of discovery, some systems belonging to ride-sharing service Uber were still at risk, though they have since patched the issue. An attacker could exploit this bug to carry out a buffer overflow, and then gain the ability to remotely execute code on the victim machine.

Title: VMware vulnerability leads to other flaws in NVIDIA Windows GPU display driver
Description: VMware ESXi, Workstation and Fusion are affected by an out-of-bounds read vulnerability that can be triggered using a specially crafted shader file. This vulnerability can be triggered from a VMware guest, affecting the VMware host, leading to a crash (denial-of-service) of the vmware-vmx.exe process on the host. However, when the host/guest systems are using an NVIDIA graphics card, the VMware denial-of-service can be turned into a code execution vulnerability (leading to a VM escape), because of an additional security issue present in NVIDIA’s Windows GPU Display Driver.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: New coverage available for Godlua malware
Description: Attackers recently targeted Linux and Windows machines with respective versions of the Godlua malware. The backdoor secures its communication via DNS over HTTPS. The attackers primarily use Godlua as a distributed denial-of-service bot, even launching an HTTP flood attack against one domain.

Title: New protection rolled out for Microsoft vulnerability exploited in the wild
Description: The OceanLotus APT recently launched a new malware known as “Ratsnif,” which comes in four different variant forms. These rules fire when Ratsnif attempts to make an outbound connection to a command and control (C2) server, or if the malware attempts to download any files. Ratsnif remained undetected after its C2 went online back in August 2018, though researchers believe it’s low level of infection kept it under the radar.
