CVE-2017-1000410: Infoleak

First published: Thu Nov 30 2017(Updated: )

A vulnerability was found in the bluetooth subsystem in the Linux kernel. This flaw takes affect while processing of incoming L2CAP commands - ConfigRequest, and ConfigResponse messages as uninitialized stack variables 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 to bypass KASLR, and stack canaries protection - as both pointers and stack canaries may be leaked in this manner. This kind of flaw is considered an 'information leak' and can be used by attackers to defeat defensive protection mechanisms that would usually mitigate other flaws.
