CoreGraphics Memory Corruption - CVE-2014-4377

Apple CoreGraphics library fails to validate the input when parsing the colorspace specification of a PDF XObject resulting in a heap overflow condition. A small heap memory allocation can be overflowed with controlled data from the input in any application linked with the affected framework. Using a crafted PDF file as an HTML image and combined with a information leakage vulnerability this issue leads to arbitrary code execution. A complete 100% reliable and portable exploit for MobileSafari on IOS7.1.x. can be downloaded from github
