libsoup: libsoup: Heap buffer overflow during WebSocket receive-buffer growth

A flaw was found in libsoup. When max-incoming-payload-size is unlimited 0, SoupWebsocketConnection could grow its incoming GByteArray based on an attacker-controlled frame length until the length wrapped, causing a heap buffer overflow while reading frame data...

libsoup: libsoup: Heap buffer overflow during WebSocket client-frame masking

A flaw was found in libsoup. When constructing a masked WebSocket client frame for a very large outgoing payload, size values passed to GByteArray allocation APIs could be truncated while the masking routine still used the full length, causing a heap buffer overflow...

libsoup: libsoup: Heap buffer overflow from WebSocket Pong signal type confusion

A flaw was found in libsoup. When handling an incoming WebSocket Pong frame, SoupWebsocketConnection emitted the ::pong signal with a GByteArray pointer even though the signal is declared to pass a GBytes. Applications connecting a handler that follows the documented GBytes API can trigger heap...

libsoup: libsoup: Heap buffer overflow during WebSocket message reassembly

A flaw was found in libsoup. When reassembling fragmented WebSocket messages into a GByteArray, libsoup did not adequately cap total message size against the limits of the underlying buffer type.
