Details

Ken Mixter discovered a format string vulnerability in the
LogVHdrMessageVerb function when handling input device names. This
could allow a local attacker to cause a denial of service or possibly
execute arbitrary code.

The default compiler options for the affected release should reduce
the vulnerability to a denial of service.
