Subject: [PATCH 12/23] audio: release capture buffers
|
|
|
|
AUD_add_capture() allocates two buffers which are never released.
|
|
Add the missing calls to AUD_del_capture().
|
|
|
|
Impact: Allows vnc clients to exhaust host memory by repeatedly
|
|
starting and stopping audio capture.
|
|
|
|
Fixes: CVE-2017-8309
