Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU11687

Risk: High

CVSSv4.0: 6.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-1023

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error when Microsoft browsers access objects in memory. A remote unauthenticated attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with privileges of the current user.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's website.
