A flaw was found in libsoups SoupServer. A remote attacker could exploit a use-after-free vulnerability where the soup_server_disconnect() function frees connection objects prematurely, even if a TLS handshake is still pending. If the handshake completes after the connection object has been freed, a dangling pointer is accessed, leading to a server crash and a Denial of Service.

Weakness

The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid.
