A flaw was found in glib-networking. A malicious Transport Layer Security (TLS) server can exploit an out-of-bounds read and invalid free vulnerability when a client using the OpenSSL backend connects. By advertising a specially crafted client-CA list, the server can trigger an issue where memory is accessed outside of its allocated buffer and subsequently freed incorrectly. This can lead to a denial-of-service and potentially disclose limited heap memory.
