When: Thu Aug 11, 2011, 6:30-8:00 PM, followed by pizza at Patsy's. Who: Avi Drissman, a developer on Google Chrome for Mac, will be our guest speaker.
What: Avi's working title is "Allocators Gonna Allocate": An unchecked allocation is an unfortunately popular security hole. Untrustworthy data can specify buffer sizes that cannot be allocated, and if the processing code doesn't handle a null return from a memory allocator, that null pointer can be abused for things like remote code execution. As defense against this, Google Chrome modifies the system memory allocators so that if they fail to allocate memory, they will crash rather than return null. But how does it do that? There are a surprising number of allocators, and not all of them provide the functionality needed to implement this critical safety feature. Come see how Chrome makes it happen anyway.
