1) Stack-based buffer overflow

EUVDB-ID: #VU8329

Risk: Low

CVSSv3.1: 8.6 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-1000251

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: Yes

Description

The vulnerability allows an adjacent attacker to execute arbitrary code on the host system.

The weakness exists due to a stack-based buffer overflow in the processing of L2CAP configuration. An adjacent attacker can submit a specially crafted Bluetooth protocol, trigger memory corruption in the Bluetooth stack and execute arbitrary code in kernel space.

Successful exploitation of the vulnerability may result in host system compromise.

Mitigation

Update the affected packages.

Vulnerable software versions

Linux kernel: 3.3 - 4.13.1
