OpenSSL Heartbleed Vulnerability (CVE-2014-0160) does not affect Documentum systems because simply these don’t use OpenSSL! Some concerns just about the on premise edition of Syncplicty.
Due to a missing bounds check in OpenSSL during the TLS heartbeat extension, up to 64k of memory can be revealed to a connected client or server. This may potentially allow an unauthenticated, remote attacker to gain access to sensitive information such as private keys, login passwords, and encryption keys (Secret Keys). As a result of this disclosure of sensitive information, these Secret Keys can potentially be leveraged to decrypt other sensitive information or conduct so-called man-in-the-middle attacks.References:
