In the yajl-ruby gem 1.3.0 for Ruby, when a crafted JSON file is supplied
to Yajl::Parser.new.parse, the whole ruby process crashes with a SIGABRT in
the yajl_string_decode function in yajl_encode.c. This results in the whole
ruby process terminating and potentially a denial of service.

| sbeattie | issue in embedded copy of yajl, looks to affect upstream yajl, too |
| rodrigo-zaiden | as of 2023-06-07, upstream yajl hasn’t fixed it, only the embedded copy in ruby-yajl got fixed. even though the code around this fix is similar between yajl and ruby-yajl, the risk of patching one based in the other could be risky without upstream support. |
