Use-after-free vulnerability in WebKit/Source/core/editing/VisibleUnits.cpp in Blink, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code involving an @import at-rule in a Cascading Style Sheets (CSS) token sequence in conjunction with a rel=import attribute of a LINK 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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
