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).

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>

<p>
|
||
|

There is no known workaround at this time.
