WebKit: use-after-free in WebCore::AXObjectCache::performDeferredCacheUpdate(CVE-2017-13795)

2017-11-23T00:00:00

Description

There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of WebKit nightly. Note that accessibility features need to be enabled in order to trigger this bug. On Safari on Mac this can be accomplished by opening the inspector (simply opening the inspector enables accessibility features). On WebKitGTK+ (and possibly other WebKit releases) accessibility features are enabled by default. ### ASan log: ``` ================================================================= ==30369==ERROR:
