CVE-2009-3621 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3621):
  net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows
  local users to cause a denial of service (system hang) by creating an
  abstract-namespace AF_UNIX listening socket, performing a shutdown
  operation on this socket, and then performing a series of connect
  operations to this socket.
