An issue was discovered in LINBIT csync2 through 2.0. It does not correctly check for the return value GNUTLS_E_WARNING_ALERT_RECEIVED of the gnutls_handshake() function. It neglects to call this function again, as required by the design of the API.

Weakness

The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.
