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.
