The impact of this vulnerability is a buffer overflow of up to a full TCP receive-window (by default, 10k-64k depending on version). The buffer overflow happens in the task calling recv()/recvfrom()/recvmsg().
Applications that pass a buffer equal to or larger than a full TCP-window are not susceptible to this attack. Applications passing a stack-allocated variable as a buffer are the easiest to exploit.
The most likely outcome is a crash of the application reading from the affected socket, which could result in remote code execution.
This plugin only works with Tenable.ot.
