 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.
