gRPC is vulnerable to Denial Of Service (DoS). The vulnerability exists because the file descriptor is not properly handled, which leads to the termination of the connection between a proxy and a backend when a hpack table accounting errors occur, allowing an attacker to cause an application crash by providing a maliciously crafted request through the HPACK parser.
