{"id":"CVE-2023-1428","summary":"Denial-of-Service in gRPC","details":"There exists an vulnerability causing an abort() to be called in gRPC. \nThe following headers cause gRPC's C++ implementation to abort() when called via http2:\n\nte: x (x != trailers)\n\n:scheme: x (x != http, https)\n\ngrpclb_client_stats: x (x == anything)\n\nOn top of sending one of those headers, a later header must be sent that gets the total header size past 8KB.
