Multiple flaws in the MadWifi driver were discovered that could lead to a system crash. A physically near-by attacker could generate specially crafted wireless network traffic and cause a denial of service. CVE-2006-7177, CVE-2006-7178, CVE-2006-7179, CVE-2007-2829, CVE-2007-2830 A flaw was...

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

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 athbeaconconfig function in...

Bluetooth setsockopt() information leaks

The setsockopt function in the L2CAP and HCI Bluetooth support in the Linux kernel before 2.4.34.3 allows context-dependent attackers to read kernel memory and obtain sensitive information via unspecified vectors involving the copyfromuser function accessing an uninitialized stack buffer...

Integer overflow

Integer underflow in the cpusettasksread function in the Linux kernel before 2.6.20.13, and 2.6.21.x before 2.6.21.4, when the cpuset filesystem is mounted, allows local users to obtain kernel memory contents by using a large offset when reading the /dev/cpuset/tasks file...

CVE-2007-2875
