Citrix Provisioning Services StreamProcess.exe 0x40020010 Packet Handling RCE

Critical Nessus Plugin ID 51664


The remote Windows host has an application running that is affected by a remote code execution vulnerability.


The version of the StreamProcess.exe component included with the Citrix Provisioning Services installation running on the remote Windows host fails to validate user-supplied input in a packet type of 0x40020010 before copying it into a fixed length buffer on the stack.
An unauthenticated, remote attacker can exploit this, via a specially crafted 0x40020010 packet sent to UDP port 6095, to execute arbitrary code on the remote host with SYSTEM privileges.


Apply the relevant patch referenced in the vendor's advisory.
