Package name madwifi-source Date April 11th, 2007 Advisory ID MDKSA-2007:082 Affected versions 2007.0, 2007.1 Synopsis Updated madwifi-source, wpa_supplicant packages fix vulnerabilities

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.
