The kernel in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to cause a denial of service via a crafted app.
The kernel in Apple iOS before 9.3, tvOS before 9.2, and watchOS before 2.2 does not properly restrict the execute permission, which allows attackers to bypass a code-signing protection mechanism via a crafted app.
Use-after-free vulnerability in the kernel in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to execute arbitrary code in a privileged context via a crafted app.
IOHIDFamily in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to obtain sensitive kernel memory-layout information via a crafted app.
FontParser in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDF document.
expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed, and each affected application would need its own CVE.
