Description

Found by oss-fuzz:
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=67562

I would rate this critical : can allocate up to 4Gbytes of memory with 128 kbytes of traffic...

We have one bound of 65k for the maximum "dynamic headers table" size, but this can get multiplied by an arbitrary number of bytes representing one compressed header.

Not sure to backport it for 6 as HTTP2 is experimental there
