Stack-based buffer overflow in net80211/ieee80211_wireless.c in MadWifi before 0.9.2.1 allows remote attackers to execute arbitrary code via unspecified vectors, related to the encode_ie and giwscan_cb functions.

The madwifi-ng Atheros Wireless LAN card driver is subject to a remotely exploitable stack-based buffer overflow, this update fixes this problem. (CVE-2006-6332)

This update also brings madwifi to version 0.9.2.1.

Laurent Butti, Jerome Razniewski, and Julien Tinnes discovered that the MadWifi wireless driver did not correctly check packet contents when receiving scan replies. A remote attacker could send a specially crafted packet and execute arbitrary code with root privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The 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.
  Impact :

    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.
  Workaround :

    There is no known workaround at this time.
