PDFium in Google Chrome before 53.0.2785.89 on Windows and OS X and before 53.0.2785.92 on Linux mishandles timers, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted PDF document, related to fpdfsdk/javascript/JS_Object.cpp and fpdfsdk/javascript/app.cpp.
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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
