07 Dec 2017 — The Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies in the processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages. This info leak is a result of uninitialized stack variables that may be returned to an attacker in their uninitialized state. By manipulating the code flows that precede the handling of these configuration messages, an attacker can also gain some control over which data will be held in the uninitialized stack variables. This can allow him t... • http://seclists.org/oss-sec/2017/q4/357 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
