macosx-corefoundation-cfdatareplacebytes-bo (42709) The risk level is classified as HighHigh Risk

Description:

Apple Mac OS X is vulnerable to a heap-based buffer overflow, caused by an integer overflow in the CoreFoundation CFDataReplaceBytes function. By creating a specially-crafted CFData object that passes an invalid length argument, a local attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the affected application to crash.
