When posting to oss-security, please include the actual detail right in
your posting (up to 200 KB including MIME overhead, but of course try to
keep it smaller than that if at all practical) - not only via external
links.  I've attached the content of the above link now.  Luckily, this
one PoC GIF file is tiny:

$ base64 poc

Ideally, you would also investigate and patch issues found by ASan,
rather than merely include its output, but I realize we can't actually
expect anything specific from volunteers.  So whatever we've got.
