host is affected by an insecure library loading vulnerability.

A remote attacker could exploit this flaw by tricking a user into
opening a legitimate Microsoft Office file located in the same
directory as a maliciously crafted dynamic link library (DLL) file,
resulting in arbitrary code execution.

Note that if an affected copy of VBE6.DLL was installed by a third-
party application, it may be necessary to contact that application's
vendor for an update.");
