Vigil@nce: Linux kernel, denial of service via e1000e
January 2010 by Vigil@nce
An attacker can send a long packet in order to stop systems with
the e1000e driver.
– Severity: 2/4
– Consequences: user 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: 30/12/2009
IMPACTED PRODUCTS
– Linux kernel
DESCRIPTION OF THE VULNERABILITY
The e1000e driver implements the support of Intel PRO/1000 network
adapters. These adapters can receive Ethernet frames with a size
of 16383 bytes (jumbo frames).
However, if the e1000e driver receives more than 16383 fragmented
bytes, 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.
