libsoup: libsoup: Heap buffer overflow during outgoing permessage-deflate buffer growth

A flaw was found in libsoup. When the permessage-deflate WebSocket extension compresses a very large outgoing message, truncated size calculations used for GByteArray growth could wrap, causing zlib to write past the allocated buffer and resulting in a heap buffer overflow...

libsoup: libsoup: Heap buffer overflow via uninitialized length in data-URI base64 decoding

A flaw was found in libsoup. The soupuridecodedatauri function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling gbase64decodeinplace. If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the si...

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 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 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. A remote peer could send fragments that caused size truncation while the implementation still used th...

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...

Astra Linux – Vulnerability in libsoup2.4

A flaw was discovered in libsoup, where the soupmessageheadersgetcontentdisposition function is vulnerable to a NULL pointer dereference. This flaw allows a malicious HTTP peer to crash a libsoup client or server that uses this function...
