Amazon Linux AMI Security Advisory: ALAS-2014-317
Advisory Release Date: 2014-09-18 00:06 Pacific
Severity: Low
References: CVE-2014-0101 

Issue Overview:

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.


Affected Packages:

kernel


Issue Correction:
Run yum update kernel to update your system. You will need to reboot your system in order for the new kernel to be running.
