Security Advisory

This security advisory describes one high risk vulnerability.

1) Out-of-bounds stack-memory write

Severity: High

CVSSv3: 8.8 [CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:U/RL:U/RC:C] [PCI]

CVE-ID: CVE-2018-18064

CWE-ID: CWE-787 - Out-of-bounds Write

Description

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

The vulnerability exists due to boundary error when during the processing of documents by the WebKitGTK+ component. A remote unauthenticated attacker can trick the victim into accessing a document that submits malicious input, trigger an out-of-bounds stack-memory write condition and cause the affected software to crash or execute arbitrary code.

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

Mitigation

Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.
