SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionThe Xen Project reports :
In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine cirrus_bitblt_cputovideo fails to check whether the specified memory region is safe. A malicious guest administrator can cause an out of bounds memory write, very likely exploitable as a privilege escalation.
