CVE-2010-4648

Published: 12 January 2012

The orinoco_ioctl_set_auth function in drivers/net/wireless/orinoco/wext.c in the Linux kernel before 2.6.37 does not properly implement a TKIP protection mechanism, which makes it easier for remote attackers to obtain access to a Wi-Fi network by reading Wi-Fi frames.

From the Ubuntu Security Team

An error was reported in the kernel's ORiNOCO wireless driver's handling of TKIP countermeasures. This reduces the amount of time an attacker needs breach a wireless network using WPA+TKIP for security.
