Apache bRPC: Out-of-bounds Read in Multi-stream RPC Response Handling
An out-of-bounds read vulnerability exists in the streaming RPC client of Apache bRPC (versions 1.11.0 through 1.17.0) on all platforms. A client that creates multiple streams in a single RPC expects the server response to carry exactly one extra_stream_id f…

Apache bRPC: Unbounded Resource Consumption and Crash in the HTTP/2 Receive Path
Uncontrolled resource consumption in the HTTP/2 (h2) receive path of Apache bRPC (version < 1.18.0) on all platforms allows a remote unauthenticated attacker to crash the server or grow its memory without bound by sending crafted HTTP/2 frames. Root Cause: Th…

Apache bRPC: Remote Denial of Service via Out-of-Bounds Dynamic Table Sizing in HPACK Decoder
A reachable-assertion flaw in the HPACK header-compression decoder of the HTTP/2 (h2/gRPC) stack in Apache bRPC (version < 1.18.0) on all platforms allows a remote attacker to crash the server process by sending a crafted sequence of HPACK headers, resulting …

Apache bRPC: Integer Underflow in mcpack2pb Parser Leading to Denial of Service
An integer underflow in the mcpack2pb component of Apache bRPC (version < 1.18.0) on all platforms allows remote attackers to crash a bRPC server by sending a request containing a string field with a zero value_size. The UnparsedValue::as_string() function co…
