Red Hat Product Errata RHSA-2010:0818 normal SHIPPED_LIVE Important: Red Hat Enterprise Virtualization Manager security update 2010-12-06 13:59:30 EST

Description Petr Matousek 2010-08-02 05:54:39 EDT
There is a race in spice-activex when a local attacker is able to create a named pipe with the expected name that is used for parameter passing (password, cert file) between spice-activex and spice client. 

Also ImpersonateNamedPipeClient() function that allows server to impersonate security context of connected user could be used to gain privileges of the spice user.
