CVE-2015-5787

TITLE

Apple iOS Vulnerability that could circumvent background execution restrictions in some kernels

Trust: 0.8

sources: JVNDB: JVNDB-2015-005998

DESCRIPTION

The kernel in Apple iOS before 8.4.1 does not properly restrict debugging features, which allows attackers to bypass background-execution limitations via a crafted app. Apple iOS for the iPhone, the iPod touch, and the iPad is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. This issue is fixed in iOS 8.4.1. Apple iOS is an operating system developed by Apple (Apple) for mobile devices. Kernel is one of the kernel components. The vulnerability stems from the fact that the program does not properly limit the debugging function
