The vulnerability could allow information disclosure if a user opened a specially crafted Web Service Discovery (.disco) file with one of the affected software listed in this bulletin. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to produce information that could be used to try to further compromise the affected system.
