Use After Free
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.
CWE-416 - Use After Free
Use-after-free (UaF) vulnerability occurs when the application is using a pointer to memory that has been freed. Any attempt to read/write to a buffer after it is de-allocated allows memory corruption, sensitive information exposure, and can potentially lead to arbitrary code execution.
