HIGH Summary
An issue was discovered in certain Apple products. iOS before 10.3.3 is affected. macOS before 10.12.6 is affected. tvOS before 10.2.2 is affected. watchOS before 3.2.3 is affected. The issue involves the "libxpc" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.
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 Mac OS X 10.10.5, Mac OS X 10.11.6, or macOS 10.12.5 and is missing a security update. It is therefore, affected by multiple vulnerabilities : - An overflow condition exists in the curl component in the dprintf_formatf() function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586) - A flaw exits in the curl component in the randit() function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594) - A flaw exists in the curl component in the allocate_conn() function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629) - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008) - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009) - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013) - Multiple memory corruption issues exist in the Intel Graphics Driver component due to improper validation of input. A local attacker can exploit these issues to execute arbitrary code with elevated privileges. (CVE-2017-7014, CVE-2017-7017, CVE-2017-7035, CVE-2017-7044) - A remote code execution vulnerability exists in the Audio component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7015) - Multiple remote code execution vulnerabilities exist in the afclip component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7016, CVE-2017-7033) - A memory corruption issue exists in the AppleGraphicsPowerManagement component due to improper validation of input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7021) - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7022, CVE-2017-7024, CVE-2017-7026) - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-7023, CVE-2017-7025, CVE-2017-7027, CVE-2017-7069) - Multiple unspecified flaws exist in the kernel due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7028, CVE-2017-7029, CVE-2017-7067) - A flaw exists in the Foundation component due to improper validation of input. A unauthenticated, remote attacker can exploit this, by convincing a user to open specially crafted file, to execute arbitrary code. (CVE-2017-7031) - A memory corruption issue exists in the |
