A local attacker could use this flaw to trickthe plug-in and the SPICE client into communicating over anattacker-controlled socket, possibly gaining access to authenticationdetails, or resulting in a man-in-the-middle attack on the SPICEconnection. (CVE-2010-2792)It was found that the SPICE Firefox plug-in used a predictable name for itslog file. A local attacker could use this flaw to conduct a symbolic linkattack, allowing them to overwrite arbitrary files accessible to the userrunning Firefox.
