Assigning to yguyon@. It doesn't look like this is even a bug with the library because it looks like it's aborting on an invalidly formatted header--maybe the fuzzer needs to be modified to not generate such test cases? Not sure.

The patch of the Issue 917029 seems to fix this bug too.
Waiting for the next sync of the public repository of libwebp
to chromium/third_party/libwebp.
