Underlying weakness

CWE-416: Use After Free

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 Any operations using the original pointer are no longer valid because the memory belongs to the code that operates on the new pointer.

Affected products

  • Google Chrome: before 5.0.375.127
  • Apple Safari: before 4.1.3; from 5.0 before 5.0.3
  • Webkitgtk: before 1.2.6
  • Apple Iphone OS: before 4.2
  • Canonical Ubuntu Linux: 9.10; 10.04; 10.10
