  desc["english"] = "

  Overview: This host has Linux Kernel Stream Control Transmission Protocol
  (SCTP) implementation and is prone to Protocol Violation Vulnerability.

  Vulnerability Insight:
  The issue is with the parameter 'sctp_paramhdr' in sctp_sf_violation_paramlen,
  sctp_sf_abort_violation, and sctp_make_abort_violation functions of sm.h,
  sm_make_chunk.c, and sm_statefunc.c files, which has invalid length and
  incorrect data types in function calls.

  Impact: Successful attacks will result in denial of service via kernel related
  vectors.

  Impact Level: System

  Affected Software/OS:
  Linux kernel version before 2.6.27 on all Linux Platforms.

  Fix: Upgrade to Linux kernel 2.6.27, or
  Apply the available patch from below link,
  http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.27.y.git;a=commit;h=ba0166708ef4da7eeb61dd92bbba4d5a749d6561
