Severity: 2/4

Consequences: administrator access/rights, denial of service of
computer

Provenance: LAN

Means of attack: no proof of concept, no attack

Ability of attacker: expert (4/4)

Confidence: confirmed by the editor (5/5)

Diffusion of the vulnerable configuration: high (3/3)

Creation date: 29/12/2009

IMPACTED PRODUCTS

– Linux kernel

DESCRIPTION OF THE VULNERABILITY

The e1000 driver implements the support of Intel PRO/100, 1000 and
10GbE network adapters. These adapters can receive Ethernet frames
with a size of 16383 bytes (jumbo frames).

However, if the e1000 driver receives short fragments, a memory
corruption occurs.

An attacker located on a network supporting jumbo frames can
therefore send a long frame in order to generate a denial of
service, and eventually to execute code.
