WebKit before r52784, as used in Google Chrome before 4.0.249.78 and Apple Safari before 4.0.5, permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

Various bugs in webkit have been fixed. The CVE id's are :
