The remote Amazon Linux AMI host is missing a security update.
The skb_gro_header_slow function in include/linux/netdevice.h in the
Linux kernel before 220.127.116.11, when Generic Receive Offload (GRO) is
enabled, resets certain fields in incorrect situations, which allows
remote attackers to cause a denial of service (system crash) via
crafted network traffic.
Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in
the eCryptfs subsystem in the Linux kernel before 3.1 allows local
users to bypass intended file permissions via a mount.ecryptfs_private
mount with a mismatched uid.
The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before
3.1 use a modified MD4 algorithm to generate sequence numbers and
Fragment Identification values, which makes it easier for remote
attackers to cause a denial of service (disrupted networking) or
hijack network sessions by predicting these values and sending crafted
Integer signedness error in the CIFSFindNext function in
fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS
servers to cause a denial of service (memory corruption) or possibly
have unspecified other impact via a large length value in a response
to a read request for a directory.
The Performance Events subsystem in the Linux kernel before 3.1 does
not properly handle event overflows associated with
PERF_COUNT_SW_CPU_CLOCK events, which allows local users to cause a
denial of service (system hang) via a crafted application.

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