Problem Description:

+

The e1000 network adapters permit a variety of modifications to an + Ethernet packet when it is being transmitted. These include the + insertion of IP and TCP checksums, insertion of an Ethernet VLAN + header, and TCP segmentation offload ("TSO"). The e1000 device model + uses an on-stack buffer to generate the modified packet header when + simulating these modifications on transmitted packets.

+

When checksum offload is requested for a transmitted packet, the + e1000 device model used a guest-provided value to specify the checksum + offset in the on-stack buffer. The offset was not validated for + certain packet types.

+

Impact:

+

A misbehaving bhyve guest could overwrite memory in the bhyve + process on the host, possibly leading to code execution in the host + context.

+

The bhyve process runs in a Capsicum sandbox, which (depending on + the FreeBSD version and bhyve configuration) limits the impact of + exploiting this issue.
