CVE-2011-2497

Priority
Description
Integer underflow in the l2cap_config_req function in
net/bluetooth/l2cap_core.c in the Linux kernel before 3.0 allows remote
attackers to cause a denial of service (heap memory corruption) or possibly
have unspecified other impact via a small command-size value within the
command header of a Logical Link Control and Adaptation Protocol (L2CAP)
configuration request, leading to a buffer overflow.
Ubuntu-Description
Dan Rosenberg discovered that the Bluetooth stack incorrectly handled
certain L2CAP requests. If a system was using Bluetooth, a remote attacker
could send specially crafted traffic to crash the system or gain root
privileges.
