Use-after-free vulnerability in the FormAssociatedElement::formRemovedFromTree function in core/html/FormAssociatedElement.cpp in Blink, as used in Google Chrome before 32.0.1700.76 on Windows and before 32.0.1700.77 on Mac OS X and Linux, allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging improper handling of the past names map of a FORM element.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
