Attack vector
LOCAL Attack complexity
LOW Privileges required
NONE Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
An issue was discovered in certain Apple products. macOS before 10.12.5 is affected. The issue involves the "Intel Graphics Driver" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

| description | The remote host is running a version of macOS that is 10.12.x prior to 10.12.5. It is, therefore, affected by multiple vulnerabilities : - Multiple memory corruption issues exist in the Kernel component that allow a local attacker to gain kernel-level privileges. (CVE-2017-2494, CVE-2017-2546) - A state management flaw exists in the iBooks component due to improper handling of URLs. An unauthenticated, remote attacker can exploit this, via a specially crafted book, to open arbitrary websites without user permission. (CVE-2017-2497) - A local privilege escalation vulnerability exists in the Kernel component due to a race condition. A local attacker can exploit this to execute arbitrary code with kernel-level privileges. (CVE-2017-2501) - An information disclosure vulnerability exists in the CoreAudio component due to improper sanitization of user-supplied input. A local attacker can exploit this to read the contents of restricted memory. (CVE-2017-2502) - A memory corruption issue exists in the Intel graphics driver component that allows a local attacker to execute arbitrary code with kernel-level privileges. CVE-2017-2503) - Multiple information disclosure vulnerabilities exist in the Kernel component due to improper sanitization of user-supplied input. A local attacker can exploit these to read the contents of restricted memory. (CVE-2017-2507, CVE-2017-2509, CVE-2017-2516, CVE-2017-6987) - A memory corruption issue exists in the Sandbox component that allows an unauthenticated, remote attacker to escape an application sandbox. (CVE-2017-2512) - A use-after-free error exists in the SQLite component when handling SQL queries. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in the execution of arbitrary code. (CVE-2017-2513) - Multiple buffer overflow conditions exist in the SQLite component due to the improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, via a specially crafted SQL query, to execute arbitrary code. (CVE-2017-2518, CVE-2017-2520) - A memory corruption issue exists in the SQLite component when handling SQL queries. An unauthenticated, remote attacker can exploit this, via a specially crafted SQL query, to execute arbitrary code. (CVE-2017-2519) - An unspecified memory corruption issue exists in the TextInput component when parsing specially crafted data. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-2524) - A flaw exists in the CoreAnimation component when handling specially crafted data. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2017-2527) - A race condition exists in the DiskArbitration feature that allow a local attacker to gain system-level privileges. (CVE-2017-2533) - An unspecified flaw exists in the Speech Framework that allows a local attacker to escape an application sandbox. (CVE-2017-2534) - A resource exhaustion issue exists in the Security component due to improper validation of user-supplied input. A local attacker can exploit this to exhaust resources and escape an application sandbox. (CVE-2017-2535) - Multiple memory corruption issues exist in the WindowServer component that allow a local attacker to execute arbitrary code with system-level privileges. (CVE-2017-2537, CVE-2017-2548) - An information disclosure vulnerability exists in WindowServer component in the _XGetConnectionPSN() function due to improper validation of user-supplied input. A local attacker can exploit this to read the contents of restricted memory. (CVE-2017-2540) - A stack-based buffer overflow condition exists in the WindowServer component in the _XGetWindowMovementGroup() function due to improper validation of user-supplied input. A local attacker can exploit this to execute arbitrary code with the privileges of WindowServer. (CVE-2017-2541) - Multiple memory corruption issues exist in the Multi-Touch component that allow a local attacker to execute arbitrary code with kernel-level privileges. (CVE-2017-2542, CVE-2017-2543) - A use-after-free error exists in the IOGraphic component that allows a local attacker to execute arbitrary code with kernel-level privileges. (CVE-2017-2545) - A flaw exists in the Speech Framework, specifically within the speechsynthesisd service, due to improper validation of unsigned dynamic libraries (.dylib) before being loaded. A local attacker can exploit this to bypass the application |
