Description

This security bulletin contains information about 13 secuirty vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-4462)

The vulnerability allows a local attacker to obtain potentially sensitive information on the target system.

The weakness exists due to insufficient input validation in the AMD component. A local attacker can supply specially crafted files and read restricted memory.


2) Memory corruption (CVE-ID: CVE-2018-4463)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to boundary error in the Carbon Core component. A local attacker can run a specially crafted application, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.


3) Out-of-bounds read (CVE-ID: CVE-2018-4434)

The vulnerability allows a local attacker to obtain potentially sensitive information or cause DoS condition on the target system.

The weakness exists due to insufficient input validation in the Intel Graphics Driver component. A local attacker can supply specially crafted files, trigger out-of-bounds read condition and cause unexpected system termination or read kernel memory.


4) Memory corruption (CVE-ID: CVE-2018-4449)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to boundary error in the WindowServer component. A local attacker can run a specially crafted application, 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-2018-4450)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to boundary error in the WindowServer component. A local attacker can run a specially crafted application, 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-2018-4461)

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.


7) 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.


8) 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.


9) 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.


10) 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.


11) 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.


12) Memory corruption (CVE-ID: CVE-2018-4465)

The vulnerability allows a local attacker to gain elevated privileges on the target system.

The weakness exists due to boundary error in the Disk Images component. A local attacker can run a specially crafted application, trigger memory corruption and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.


13) 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.
