Detailsinfo

A vulnerability was found in MadWifi 0.9.0/0.9.1/0.9.2/0.9.2.1/0.9.3 (Wireless LAN Software). It has been declared as problematic. This vulnerability affects some unknown processing of the file net80211/ieee80211_input.c of the component net80211. The manipulation with an unknown input leads to a null pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. As an impact it is known to affect availability. CVE summarizes:

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.

The weakness was disclosed 05/23/2007 (Website). The advisory is shared for download at madwifi.org. This vulnerability was named CVE-2007-2829 since 05/23/2007. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are known technical details, but no exploit is available.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 25474 (GLSA-200706-04 : MadWifi: Multiple vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks.
