Gentoo Linux Security Advisory

Title: MadWifi: Multiple vulnerabilities (GLSA 200706-04)
Severity: high
Exploitable: remote
Date: June 11, 2007
Bug(s): #179532
ID: 200706-04

Synopsis

Multiple vulnerabilities have been discovered in MadWifi, possibly allowing for the execution of arbitrary code or a Denial of Service.

Background

The MadWifi driver provides support for Atheros based IEEE 802.11 Wireless Lan cards.

Affected Packages

Package: net-wireless/madwifi-ng
Vulnerable: < 0.9.3.1
Unaffected: >= 0.9.3.1
Architectures: All supported architectures


Description

Md Sohail Ahmad from AirTight Networks has discovered a divison by zero in the ath_beacon_config() function (CVE-2007-2830). The vendor has corrected an input validation error in the ieee80211_ioctl_getwmmparams() and ieee80211_ioctl_getwmmparams() functions(CVE-207-2831), and an input sanitization error when parsing nested 802.3 Ethernet frame lengths (CVE-2007-2829).

Impact

An attacker could send specially crafted packets to a vulnerable host to exploit one of these vulnerabilities, possibly resulting in the execution of arbitrary code with root privileges, or a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All MadWifi users should upgrade to the latest version:
