A flaw was found in libstrophe. A malicious XMPP (Extensible Messaging and Presence Protocol) server can exploit a stack-based buffer overflow in the SCRAM (Salted Challenge Response Authentication Mechanism) authentication handler by sending an oversized salt value. This issue allows an attacker to cause the client application to crash, resulting in a Denial of Service (DoS), or potentially corrupt stack memory.
