"According to its self-reported version, Cisco Jabber is affected by a vulnerability due to improper validation of
message contents. An authenticated, remote attacker can exploit this, by sending specially crafted messages that contain
Universal Naming Convention (UNC) links to a targeted user and convincing the user to follow the provided link in order
to cause the application to access a remote system, possibly allowing the attacker to gain sensitive information.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
