-Subject: [PATCH] libertas: Fix two buffer overflows at parsing bss descriptor
-Date: Fri, 22 Nov 2019 13:29:17 +0800
-Message-Id: <20191122052917.11309-1-huangwenabc@gmail.com>
-X-Mailer: git-send-email 2.17.1
-Sender: linux-wireless-owner@vger.kernel.org

-From: Wen Huang <huangwenabc@gmail.com>
-
-add_ie_rates() copys rates without checking the length 
-in bss descriptor from remote AP.when victim connects to 
-remote attacker, this may trigger buffer overflow.
-lbs_ibss_join_existing() copys rates without checking the length 
-in bss descriptor from remote IBSS node.when victim connects to 
-remote attacker, this may trigger buffer overflow.
-Fix them by putting the length check before performing copy.
-
-This fix addresses CVE-2019-14896 and CVE-2019-14897.
