Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Memory corruption

EUVDB-ID: #VU16303

Risk: High

CVSSv3.1: 8.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-4437

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 weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update to version 2.22.5.

Vulnerable software versions

WebKitGTK+: 2.15.3 - 2.22.4
