"The remote host is running a version of CA Vet Scan Engine that is
vulnerable to heap overflow. An attacker may exploit this flaw to
execute arbitrary code on the remote host with the privileges of a

To exploit this flaw, an attacker would need to send a specially-
crafted file to the remote antivirus library.");
