Detailsinfo

A vulnerability was found in Apple Mac OS X 10.8.5/10.9.5/10.10/10.10.1 (Operating System) and classified as critical. Affected by this issue is some unknown functionality of the component Intel Graphics Driver. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:
