Mandrake Linux Security Advisory : madwifi-source (MDKSA-2007:132)

critical Nessus Plugin ID 25598

Synopsis

The remote Mandrake Linux host is missing one or more security updates.

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.

Solution

Update the affected madwifi-source, wpa_gui and / or wpa_supplicant packages.
