Vulnerabilities > CVE-2016-4681 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Apple mac OS X
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 10.12.1 is affected. The issue involves the "Core Image" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted JPEG file.
Vulnerable Configurations
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 Mac OS X that is 10.10.5 but is missing Security Update 2016-006, or else it is version 10.11.6 but is missing Security Update 2016-002. It is, therefore, affected by multiple vulnerabilities : - A memory corruption issue exists in the AppleGraphicsControl component due to improper lock state checking. A local attacker can exploit this, via a specially crafted application, to execute arbitrary code with kernel-level privileges. (CVE-2016-4662) - A memory corruption issue exists in the NVIDIA Graphics Driver due to improper validation of user-supplied input. A local attacker can exploit this to cause a denial of service condition. (CVE-2016-4663) - Multiple flaws exist in the System Boot component due to improper validation of user-supplied input. A local attacker can exploit these to terminate the system or execute arbitrary code with kernel-level privileges. (CVE-2016-4669) - An out-of-bounds write error exists in the ImageIO component when parsing PDF files due to improper bounds checking. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted PDF file, to execute arbitrary code. (CVE-2016-4671) - A memory corruption issue exists in the Core Image component when handling JPEG files due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to open a specially crafted JPEG file, to execute arbitrary code. (CVE-2016-4681) - An out-of-bounds read error exists in the ImageIO component when parsing specially crafted SGI images. An unauthenticated, remote attacker can exploit this to disclose potentially sensitive information in process memory. (CVE-2016-4682) - Multiple out-of-bounds read and write errors exist in the ImageIO component when parsing specially crafted SGI images. An unauthenticated, remote attacker can exploit these to disclose potentially sensitive information, cause a denial of service condition, or execute arbitrary code. (CVE-2016-4683) |
