Vulnerability from variot
An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 12.1.3, macOS Mojave 10.14.3, iTunes 12.9.3 for Windows. A malicious application may be able to elevate privileges. Apple iOS , macOS , iTunes Contains an out-of-bounds reading vulnerability due to a flaw in processing related to boundary checking.Malicious applications can elevate privileges. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Sandbox avoidance * Arbitrary code execution * Privilege escalation * information leak * Information falsification * Service operation interruption (DoS) * Arbitrary script execution. 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 handling of crte messages within the mediaserverd service. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Apple iOS and macOS are prone to multiple security vulnerabilities. Failed exploit attempts will likely cause a denial-of-service condition. in the United States. Apple iOS is a set of operating systems developed for mobile devices; macOS High Sierra and macOS Mojave are different versions of dedicated operating systems developed for Mac computers. Core Media is one of the media core components.

"data": "An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in iOS 12.1.3, macOS Mojave 10.14.3, iTunes 12.9.3 for Windows. A malicious application may be able to elevate privileges. Apple iOS , macOS , iTunes Contains an out-of-bounds reading vulnerability due to a flaw in processing related to boundary checking.Malicious applications can elevate privileges. Apple Has released an update for each product.The expected impact depends on each vulnerability, but can be affected as follows: * Sandbox avoidance * Arbitrary code execution * Privilege escalation * information leak * Information falsification * Service operation interruption (DoS) * Arbitrary script execution. 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 handling of crte messages within the mediaserverd service. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Apple iOS and macOS are prone to multiple security vulnerabilities. Failed exploit attempts will likely cause a denial-of-service condition. in the United States. Apple iOS is a set of operating systems developed for mobile devices; macOS High Sierra and macOS Mojave are different versions of dedicated operating systems developed for Mac computers. Core Media is one of the media core components. \nCVE-2018-4467: Martim Carbone, David Vernet, Sam Scalise, and Fred\nJacobs of the Virtual Machine Monitor Group of VMware, Inc. -----BEGIN PGP SIGNED
