An out-of-bounds memory write flaw was found in how the Linux kernel’s
Voice Over IP H.323 connection tracking functionality handled connections
on ipv6 port 1720. This flaw allows an unauthenticated remote user to crash
the system, causing a denial of service. The highest threat from this
vulnerability is to confidentiality, integrity, as well as system
availability.
