2) Out-of-bounds read

EUVDB-ID: #VU68830

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-8921

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to missing verification checks when handling consecutive SVC_ATTR_REQ requests within the service_attr_req() function in sdpd-request.c in bluetoothd . A remote attacker on the local network can send specially crafted CSTATE data to the system and trick the server into returning more bytes than the buffer actually holds, resulting in leaking arbitrary heap data.

Mitigation

Update the affected package bluez to the latest version.
