Vulnerabilities > CVE-2016-1719 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Apple products
Attack vector
LOCAL Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
The IOHIDFamily API in Apple iOS before 9.2.1, OS X before 10.11.3, and tvOS before 9.1.1 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors.
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.

NASL family Misc. NASL id APPLETV_9_1_1.NASL description According to its banner, the remote Apple TV device is a version prior to 9.1.1. It is, therefore, affected by the following vulnerabilities : - A type confusion error exists in the bundled libxslt library due to improper handling of invalid values. An attacker can exploit this to crash the application, resulting in a denial of service condition. (CVE-2015-7995) - A memory corruption issue exists due to improper validation of user-supplied input when handling disk images. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-1717) - A use-after-free error exists in the IOHIDFamily API due to improper validation of user-supplied input. A local attacker can exploit this to dereference already freed memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-1719) - A memory corruption issue exists in IOKit due to improper validation of user-supplied input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-1720) - A memory corruption issue exists in the Kernel due to improper validation of user-supplied input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-1721) - An overflow condition exists in the add_lockdown_session() function due to improper validation of user-supplied input. A local attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-1722) - Multiple memory corruption issues exist in WebKit due to improper validation of user-supplied input. A remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code.
