GO-2024-2687

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

GO-2024-2683

HashiCorp Consul does not properly validate the node or segment names prior to interpolation and usage in JWT claim assertions with the auto config RPC.

GO-2024-2682

An attacker can cause its peer to run out of memory by sending a large number of NEW_CONNECTION_ID frames that retire old connection IDs. The receiver is supposed to respond to each retirement frame with a RETIRE_CONNECTION_ID frame. The attacker can prevent the receiver from sending out (the vast majority of) these RETIRE_CONNECTION_ID frames by collapsing the peers congestion window (by selectively acknowledging received packets) and by manipulating the peer's RTT estimate.

GO-2024-2671

A vulnerability was identified in Nomad such that the search HTTP API can reveal names of available CSI plugins to unauthenticated users or users without the plugin:read policy. This vulnerability affects Nomad since 0.11.0 and was fixed in 1.4.11 and 1.5.7.

GO-2024-2670
