Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Memory corruption (CVE-ID: CVE-2018-4464)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
2) Memory corruption (CVE-ID: CVE-2018-4437)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
3) Memory corruption (CVE-ID: CVE-2018-4438)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger state management error and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
4) Security restrictions bypass (CVE-ID: CVE-2018-4436)
The vulnerability allows a local attacker to bypass security restrictions on the target system.
The weakness exists due insufficient validation of certificates in the Profiles component. A local attacker can bypass security restrictions and cause an untrusted configuration profile to be incorrectly displayed as verified.
5) Memory corruption (CVE-ID: CVE-2018-4441)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, 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-2018-4442)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
7) Memory corruption (CVE-ID: CVE-2018-4443)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to boundary error in the Webkit component. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
8) Memory corruption (CVE-ID: CVE-2018-4461)
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to boundary error in the Kernel component. A local attacker can run a specially crafted application, 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-2018-4447)
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to boundary error in the Kernel component. A local attacker can run a specially crafted application, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
10) Privilege escalation (CVE-ID: CVE-2018-4435)
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to a logic issue in the Kernel component. A local attacker can run a specially crafted application and gain elevated privileges.
11) Information disclosure (CVE-ID: CVE-2018-4431)
The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.
The weakness exists due to a boundary error in the Kernel component. A local attacker can trigger memory corruption and read kernel memory.
12) Denial of service (CVE-ID: CVE-2018-4460)
The vulnerability allows a local attacker to cause DoS condition on the target system.
The weakness exists due to an error in the Kernel component. A local attacker can conduct DoS attack and cause the device to crash.
13) Memory corruption (CVE-ID: CVE-2018-4427)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a boundary error in IOHIDFamily component when handling malicious input. A remote attacker can trick the victim into processing a specially crafted input, trigger memory corruption and execute arbitrary code with kernel privileges.
Successful exploitation of the vulnerability may result in system compromise.
14) Type confusion (CVE-ID: CVE-2018-4303)
The vulnerability allows a local attacker to gain elevated privileges on the target system.
The weakness exists due to type confusion in the Airport component. A local attacker can run a specially crafted application, trigger memory corruption and gain elevated privileges.
