Summary XSSAuditor memory leak when posting large form

Reported 2014-10-30 13:17:47 PDT
Created attachment 240690 [details] HTML file that causes Mobile Safari to crash. Submitting certain forms to any endpoint that returns any response will cause XSSAuditor and JavaScriptCore to allocate hundreds of MB in memory until the process crashes, even when the form is just 6 MB in size. Attached is a sample message. Change the form target to anything that returns any response, or return a dummy response in Fiddler. Profiling in instruments shows thousands of allocations of 528 Bytes by: WTF::MallocHook::recordAllocation WTF::fastMalloc WebCore::SuffixTree WebCore::XSSAuditor WebCore::HTMLDocumentParser ... I can send the trace if requested (it seems I'm only allowed one attachment here).
