VAR-201712-1105
Vulnerability from variot - Updated: 2025-04-20 21:22An issue was discovered in certain Apple products. iOS before 11.2 is affected. macOS before 10.13.2 is affected. tvOS before 11.2 is affected. watchOS before 4.2 is affected. The issue involves the "IOKit" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This vulnerability allows local attackers to escalate privileges on vulnerable installations of Apple iOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the backboardd service. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of root. Apple iOS/WatchOS/tvOS/macOS are prone to a memory-corruption vulnerability. Failed exploit attempts will result in 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. IOKit is one of the components that read system information. The following products and versions are affected: Apple iOS prior to 11.2; macOS High Sierra prior to 10.13.2; tvOS prior to 11.2; watchOS prior to 4.2

"data": "An issue was discovered in certain Apple products. iOS before 11.2 is affected. macOS before 10.13.2 is affected. tvOS before 11.2 is affected. watchOS before 4.2 is affected. The issue involves the \"IOKit\" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app. This vulnerability allows local attackers to escalate privileges on vulnerable installations of Apple iOS. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.The specific flaw exists within the backboardd service. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this in conjunction with other vulnerabilities to execute code under the context of root. Apple iOS/WatchOS/tvOS/macOS are prone to a memory-corruption vulnerability. Failed exploit attempts will result in 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. IOKit is one of the components that read system information. The following products and versions are affected: Apple iOS prior to 11.2; macOS High Sierra prior to 10.13.2; tvOS prior to 11.2; watchOS prior to 4.2",
