GLSA-200612-09 : MadWifi: Kernel driver buffer overflow
High Nessus Plugin ID 23861
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200612-09 (MadWifi: Kernel driver buffer overflow)
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.
SolutionAll MadWifi users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-wireless/madwifi-ng-0.9.2.1'
