CWE-476  (opens in a new tab)

How to fix?

Upgrade RHEL:6 kernel-firmware to version 0:2.6.32-431.11.2.el6 or higher.
This issue was patched in RHSA-2014:0328.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-firmware package and not the kernel-firmware package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk.
