libsoup: SoupWebsocketConnection: libsoup: WebSocket remote denial of service via oversized control frame protocol violation

A vulnerability was found in libsoup's WebSocket frame parsing implementation. The library fails to validate length rules specified in RFC 6455 §5.5, which mandates that all WebSocket control frames e.g., PING, PONG, CLOSE contain a payload of 125 bytes or less. A remote, unauthenticated attacker...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of validation on attacker-controlled counts and lengths in the SPDY/3 frame parser. An attacker can exhaust process memory and cause an out-of-memory crash by sending ...

CVE-2026-35469

spdystream is a Go library for SPDY multiplexing. In versions ≤ 0.5.0, the SPDY/3 frame parser allocates memory for SETTINGS counts, header counts, and header field sizes without proper bounds checking, enabling large on-the-wire values to exhaust memory via crafted control frames. A remote peer ...

CVE-2026-35469

spdystream is a Go library for multiplexing streams over SPDY connections. In versions 0.5.0 and below, the SPDY/3 frame parser does not validate attacker-controlled counts and lengths before allocating memory. Three allocation paths are affected: the SETTINGS frame entry count, the header count ...
