Security Bulletin
This security bulletin contains information about 8 vulnerabilities.
1) Memory corruption
EUVDB-ID: #VU10201
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-2018-4088
CWE-ID:
CWE-119 - Memory corruption
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the WebKit component when processing maliciously crafted web content. A remote 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 the vulnerability may result in system compromise.
