Vulnerability from variot
Login Window in Apple OS X before 10.11.6 allows attackers to execute arbitrary code in a privileged context, obtain sensitive user information, or cause a denial of service (memory corruption) via a crafted app. The issue lies in the failure to properly validate user-supplied data which can result in a memory corruption condition. 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 CoreGraphics. By interacting with _XRegisterCursorWithData, an attacker can cause a heap buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code under the context of the WindowServer. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. Apple Mac OS X 10.9.5, 10.10.5 and 10.11 through 10.11.5 are vulnerable. Login Window is one of the login window components
