Vulnerability from variot
Integer overflow in the dtrace implementation in the kernel in Apple OS X before 10.11.5 allows attackers to execute arbitrary code in a privileged context via a crafted app. Supplementary information : CWE Vulnerability types by CWE-190: Integer Overflow or Wraparound ( Integer overflow or wraparound ) Has been identified. 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 the dtrace facility. The issue lies with the failure to validate user-supplied chunk size values which can lead to arbitrary read and write of memory. 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 10.11.4 are vulnerable. Kernel is one of the kernel components

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 the dtrace facility. The issue lies with the failure to validate user-supplied chunk size values which can lead to arbitrary read and write of memory. \nAttackers 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. \nApple Mac OS X 10.9.5, 10.10.5 and 10.11 through 10.11.4 are vulnerable.
