Use-after-free vulnerability in WebKit, as used in Apple iTunes before 10.2 on Windows, Apple Safari, and Google Chrome before 6.0.472.59, allows remote attackers to execute arbitrary code or cause a denial of service via vectors related to SVG styles, the DOM tree, and error messages.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
