This updates fixes following security problems:
- CVE-2007-2829: The 802.11 network stack in net80211/ieee80211_input.c in MadWifi before 0.9.3.1 allows 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-2007-2830: The ath_beacon_config function in if_ath.c in MadWifi before 0.9.3.1 allows remote attackers to cause a denial of service (system crash) via crafted beacon interval information when scanning for access points, which triggers a divide-by-zero error.
- CVE-2007-2831: Array index error in the (1) ieee80211_ioctl_getwmmparams and (2) ieee80211_ioctl_setwmmparams functions in net80211/ieee80211_wireless.c in MadWifi before 0.9.3.1 allows local users to cause a denial of service (system crash), possibly obtain kernel memory contents, and possibly execute arbitrary code via a large negative array index value.
Please note that the problems fixed in 0.9.3 were fixed by the madwifi Version upgrade to 0.9.3 in SLE10 Service Pack 1. (CVE-2005-4835, CVE-2006-7177, CVE-2006-7178, CVE-2006-7179, CVE-2006-7180).
