CVE-2011-1059

Use-after-free vulnerability in WebCore in WebKit before r77705, as used in Google Chrome before 11.0.672.2 and other products, allows user-assisted remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via vectors that entice a user to resubmit a form, related to improper handling of provisional items by the HistoryController component, aka rdar problem 8938557.

Weakness

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
