Chrome Apps in Google Chrome prior to 57.0.2987.98 for Linux, Windows, and Mac had a use after free bug in GuestView, which allowed a remote attacker to perform an out of bounds memory read via a crafted Chrome extension.
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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
