Security Bulletin

This security bulletin contains one low risk vulnerability.

1) Buffer overflow

EUVDB-ID: #VU22712

Risk: Low

CVSSv4.0: 2.1 [CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-12207

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a local user to perform denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the mechanism responsible for error handling on some Intel platforms. A local user of a guest operating system can use a specially crafted application to trigger memory corruption and cause the host system to stop responding.

Successful exploitation of this vulnerability may result in a denial of service (DoS) attack.
