Description
This security bulletin contains information about 9 vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2019-6212)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 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
The vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists due to a boundary error in the WebKit component when handling malicious input. A remote attacker can trick the victim into processing a specially crafted content, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
2) Type confusion (CVE-ID: CVE-2019-6215)
CWE-ID: CWE-843 - Type confusion
CVSSv4: 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
The vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists due to a boundary error in the WebKit component when handling malicious input. A remote attacker can trick the victim into processing a specially crafted content, trigger type confusion error and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
