 Mandriva Linux Security Advisory                         MDKSA-2007:082
 http://www.mandriva.com/security/
 _______________________________________________________________________
 
 Package : madwifi-source
 Date    : April 11, 2007
 Affected: 2007.0, 2007.1
 _______________________________________________________________________
 
 Problem Description:
 
 The ath_rate_sample function in the ath_rate/sample/sample.c sample
 code in MadWifi before 0.9.3 allows remote attackers to cause a denial
 of service (failed KASSERT and system crash) by moving a connected
 system to a location with low signal strength, and possibly other
 vectors related to a race condition between interface enabling and
 packet transmission. (CVE-2005-4835)
 
 MadWifi, when Ad-Hoc mode is used, allows remote attackers to cause
 a denial of service (system crash) via unspecified vectors that lead
 to a kernel panic in the ieee80211_input function, related to packets
 coming from a malicious WinXP system. (CVE-2006-7177)
 
 MadWifi before 0.9.3 does not properly handle reception of an AUTH
 frame by an IBSS node, which allows remote attackers to cause a denial
 of service (system crash) via a certain AUTH frame. (CVE-2006-7178)
 
 ieee80211_input.c in MadWifi before 0.9.3 does not properly process
 Channel Switch Announcement Information Elements (CSA IEs), which
 allows remote attackers to cause a denial of service (loss of
 communication) via a Channel Switch Count less than or equal to one,
 triggering a channel change. (CVE-2006-7179)
 
 ieee80211_output.c in MadWifi before 0.9.3 sends unencrypted packets
 before WPA authentication succeeds, which allows remote attackers
 to obtain sensitive information (related to network structure),
 and possibly cause a denial of service (disrupted authentication)
 and conduct spoofing attacks. (CVE-2006-7180)
 
 Updated packages have been updated to 0.9.3 to correct this
 issue. Wpa_supplicant is built using madwifi-source and has been
 rebuilt using 0.9.3 source.
