CVE Reference:   CVE-2018-4082, CVE-2018-4084, CVE-2018-4085, CVE-2018-4086, CVE-2018-4088, CVE-2018-4089, CVE-2018-4090, CVE-2018-4091, CVE-2018-4092, CVE-2018-4093, CVE-2018-4094, CVE-2018-4096, CVE-2018-4097, CVE-2018-4098, CVE-2018-4100   (Links to External Site)
Date:  Jan 24 2018
Impact:   Denial of service via network, Disclosure of system information, Execution of arbitrary code via network, User access via local system, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Multiple vulnerabilities were reported in Apple macOS/OS X. A remote user can cause arbitrary code to be executed on the target user's system. A remote user can cause denial of service conditions on the target system. An application can obtain potentially sensitive information from system memory. An application can obtain elevated privileges on the target system. A remote user can bypass security controls on the target system.

A remote user can trigger a memory corruption error in the Audio component to execute arbitrary code [CVE-2018-4094].

An application can trigger a memory corruption error in the IOHIDFamily component to execute arbitrary code with kernel privileges [CVE-2018-4098].

An application can trigger a memory handling error in the the kernel component to read restricted memory [CVE-2018-4090].

An application can trigger a race condition in the the kernel component to read restricted memory [CVE-2018-4092].

An application can trigger a memory corruption error in the the kernel component to execute arbitrary code with kernel privileges [CVE-2018-4082].

An application can trigger a logic error in the the kernel component to execute arbitrary code with kernel privileges [CVE-2018-4097].

An application can trigger a input validation flaw in the the kernel component to read restricted memory [CVE-2018-4093].

A remote user can send a specially crafted text message to cause the LinkPresentation component to consume all available resources and deny denial of service to the application [CVE-2018-4100].

A remote user can trigger a memory corruption error in the QuartzCore component to execute arbitrary code [CVE-2018-4085].

A sandboxed process can bypass Sandbox restrictions [CVE-2018-4091].

A user can cause the Security component to incorrectly apply certificate name constraints [CVE-2018-4086].

A remote user can trigger a memory corruption error in the WebKit component to execute arbitrary code [CVE-2018-4088, CVE-2018-4089, CVE-2018-4096].

An application can trigger a input validation flaw in the Wi-Fi component to read restricted memory [CVE-2018-4084].

(via Trend Micro's Zero Day Initiative), Russ Cox of Google, Siguza, and an anonymous researcher reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A remote user can cause denial of service conditions.

A local user can obtain potentially sensitive information from system memory on the target system.

A local user can obtain elevated privileges on the target system.

A remote user can bypass security controls on the target system.

Solution:   The vendor has issued a fix (10.13.3, Security Update 2018-001 Sierra, and Security Update 2018-001 El Capitan).

The vendor advisory is available at:
