CVE-2023-33953

CVE-2023-33953 concerns the gRPC HPACK parser. Multiple vectors cause denial-of-service via: (1) unbounded memory buffering due to header size checks behind string reads, (2) unbounded CPU due to per-input-block memory copies creating an 0(n^2) parsing loop, (3) HPACK varints that can start with ...
