What is CVE-2018-20378?
CVE-2018-20378 is a high-severity memory corruption vulnerability in n/a, published on 29 Mar 2019. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The L2CAP signaling channel implementation and SDP server implementation in OpenSynergy Blue SDK 3.2 through 6.0 allow remote, unauthenticated attackers to execute arbitrary code or cause a denial of service via malicious L2CAP configuration requests, in conjunction with crafted SDP communication over maliciously configured L2CAP channels. The attacker must have connectivity over the Bluetooth physical layer, and must be able to send raw L2CAP frames. This is related to L2Cap_HandleConfigReq in core/stack/l2cap/l2cap_sm.c and SdpServHandleServiceSearchAttribReq in core/stack/sdp/sdpserv.c.
