Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
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
DescriptionThe 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.
Update the affected packages.
