Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Information disclosure (CVE-ID: CVE-2018-4398)
The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to an error in the Miller-Rabin primality test. A remote attacker can incorrectly identify prime numbers.
2) Cross-site scripting (CVE-ID: CVE-2018-4374)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists 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 potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks
3) Cross-site scripting (CVE-ID: CVE-2018-4377)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists 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 potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks
4) Memory corruption (CVE-ID: CVE-2018-4378)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
5) Resource exhaustion (CVE-ID: CVE-2018-4409)
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to resource exhaustion in Webkit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, consume excessive resources and cause the service to crash.
6) Memory corruption (CVE-ID: CVE-2018-4416)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
7) Memory corruption (CVE-ID: CVE-2018-4372)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
8) Memory corruption (CVE-ID: CVE-2018-4373)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
9) Memory corruption (CVE-ID: CVE-2018-4375)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
10) Memory corruption (CVE-ID: CVE-2018-4376)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
11) Memory corruption (CVE-ID: CVE-2018-4382)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
12) Memory corruption (CVE-ID: CVE-2018-4386)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in WebKit component when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with kernel privileges.
