Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2019-6212)
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)
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.
3) Memory corruption (CVE-ID: CVE-2019-6216)
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.
4) Memory corruption (CVE-ID: CVE-2019-6217)
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.
5) Memory corruption (CVE-ID: CVE-2019-6226)
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.
6) Memory corruption (CVE-ID: CVE-2019-6227)
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.
7) Cross-site scripting (CVE-ID: CVE-2019-6229)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists in the WebKit component due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal the authentication cookies and gain access to the device.
8) Memory corruption (CVE-ID: CVE-2019-6233)
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.
9) Memory corruption (CVE-ID: CVE-2019-6234)
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.
