|Gentoo Linux Security Advisory
Title: MadWifi: Kernel driver buffer overflow (GLSA 200612-09)
Date: December 10, 2006
MadWifi is vulnerable to a buffer overflow that could potentially lead to the remote execution of arbitrary code with root privileges.
MadWifi (Multiband Atheros Driver for Wireless Fidelity) provides a Linux kernel device driver for Atheros-based Wireless LAN devices.
Vulnerable: < 0.9.2.1
Unaffected: >= 0.9.2.1
Architectures: All supported architectures
Laurent Butti, Jerome Raznieski and Julien Tinnes reported a buffer overflow in the encode_ie() and the giwscan_cb() functions from ieee80211_wireless.c.
A remote attacker could send specially crafted wireless WPA packets containing malicious RSN Information Headers (IE) that could potentially lead to the remote execution of arbitrary code as the root user.
There is no known workaround at this time.
All MadWifi users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=net-wireless/madwifi-ng-0.9.2.1"
