Vigil@nce: Solaris, denial of service of e1000g
June 2008 by Vigil@nce
SYNTHESIS
A remote attacker can block the e1000g driver in order to block
all inbound network packets.
Gravity: 3/4
Consequences: denial of service of computer
Provenance: internet client
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: 16/06/2008
Identifier: VIGILANCE-VUL-7897
IMPACTED PRODUCTS
– OpenSolaris [confidential versions]
– Sun Solaris [confidential versions]
DESCRIPTION
The e1000g drivers handles Gigabit Ethernet network interfaces.
The /usr/src/uts/common/io/e1000g/e1000g_rx.c file handles the
reception of network packets.
Network interfaces with Intel 82571/82572 controllers
automatically handle IPv6 extensions. However, the e1000g driver
does not support this behavior, which generates an error in
e1000g_rx.c.
A remote attacker can therefore send an IPv6 packet in order to
block the driver. The system will not receive new packets.
