DHCP routing options can manipulate interface-based VPN traffic

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.

A vulnerability has been discovered in the Citrix Secure Access client for Ubuntu which, if exploited, could allow an attacker to remotely execute code if a victim user opens an attacker-crafted link and accepts further prompts.

A vulnerability has been discovered in the Citrix Secure Access client for Windows which, if exploited, could allow an attacker with access to an endpoint with Standard User Account that has the vulnerable client installed to escalate their local privileges to that of NT AUTHORITY\SYSTEM.
