Multiple Ethernet Driver Frame Padding Information Disclosure (Etherleak)

low Nessus Plugin ID 11197

Language:

Synopsis

The remote host appears to leak memory in network packets.

Description

The remote host uses a network device driver that pads ethernet frames with data which vary from one packet to another, likely taken from kernel memory, system memory allocated to the device driver, or a hardware buffer on its network interface card.

Known as 'Etherleak', this information disclosure vulnerability may allow an attacker to collect sensitive information from the affected host provided he is on the same physical subnet as that host.

This plugin is prone to false positives on networks where VLAN tagging is stripped from packets prior to delivery.

Solution

Contact the network device driver's vendor for a fix.
