Mandriva Update for madwifi-source MDKSA-2007:082 (madwifi-source)

Check for the Version of madwifi-source

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.
