Mandriva Linux Security Advisory MDKSA-2007:132
http://www.mandriva.com/security/

Package : madwifi-source
Date : June 21, 2007
Affected: 2007.0, 2007.1

Problem Description:

The 802.11 network stack in MadWifi prior to 0.9.3.1 would alloa remote
attackers to cause a denial of service (system hang) via a crafted
length field in nested 802.3 Ethernet frames in Fast Frame packets,
which results in a NULL pointer dereference (CVE-2007-2829).

The ath_beacon_config function in MadWifi prior to 0.9.3.1 would
allow a remote attacker to cause a denial of service (system crash)
via crafted beacon interval information when scanning for access
points, which triggered a divide-by-zero error (CVE-2007-2830).

An array index error in MadWifi prior to 0.9.3.1 would allow a
local user to cause a denial of service (system crash) and possibly
obtain kerenl memory contents, as well as possibly allowing for the
execution of arbitrary code via a large negative array index value
(CVE-2007-2831).

Updated packages have been updated to 0.9.3.1 to correct these
issues. Wpa_supplicant is built using madwifi-source and has been
rebuilt using 0.9.3.1 source.
