Overview

MadWifi vulnerabilities


Details

Multiple flaws in the MadWifi driver were discovered that could lead
to a system crash. A physically near-by attacker could generate
specially crafted wireless network traffic and cause a denial of
service. (CVE-2006-7177, CVE-2006-7178, CVE-2006-7179, CVE-2007-2829,
CVE-2007-2830)

A flaw was discovered in the MadWifi driver that would allow unencrypted
network traffic to be sent prior to finishing WPA authentication.
A physically near-by attacker could capture this, leading to a loss of
privacy, denial of service, or network spoofing. (CVE-2006-7180)

A flaw was discovered in the MadWifi driver’s ioctl handling. A local
attacker could read kernel memory, or crash the system, leading to a
