[Qemu-devel] [PATCH 0/4] json-streamer: Fix up code to limit nesting and size

[Markus Armbruster]

We limit nesting depth and input size to defend against input
triggering excessive heap or stack memory use (commit 29c75dd
json-streamer: limit the maximum recursion depth and maximum token
count).  This limiting is flawed in multiple ways.  Fix it up some.

Not yet fixed: this JSON parser is an absurd memory hog; see last
patch.

Markus Armbruster (4):
  json-streamer: Apply nesting limit more sanely
  json-streamer: Don't crash when input exceeds nesting limit
  check-qjson: Add test for JSON nesting depth limit
  json-streamer: Limit number of tokens in addition to total size
