Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-200706-04
(MadWifi: Multiple vulnerabilities)

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.
