Scientific Linux Security Update : kernel on SL6.x i386/x86_64

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

* A flaw was found in the way the Linux kernel's futex subsystem
handled reference counting when requeuing futexes during futex_wait().
A local, unprivileged user could use this flaw to zero out the
reference counter of an inode or an mm struct that backs up the memory
area of the futex, which could lead to a use-after-free flaw,
resulting in a system crash or, potentially, privilege escalation.
(CVE-2014-0205, Important)

* A NULL pointer dereference flaw was found in the way the Linux
kernel's networking implementation handled logging while processing
certain invalid packets coming in via a VxLAN interface. A remote
attacker could use this flaw to crash the system by sending a
specially crafted packet to such an interface. (CVE-2014-3535,
Important)

* An out-of-bounds memory access flaw was found in the Linux kernel's
system call auditing implementation. On a system with existing audit
rules defined, a local, unprivileged user could use this flaw to leak
kernel memory to user space or, potentially, crash the system.
(CVE-2014-3917, Moderate)

* An integer underflow flaw was found in the way the Linux kernel's
Stream Control Transmission Protocol (SCTP) implementation processed
certain COOKIE_ECHO packets. By sending a specially crafted SCTP
packet, a remote attacker could use this flaw to prevent legitimate
connections to a particular SCTP server socket to be made.
(CVE-2014-4667, Moderate)

The system must be rebooted for this update to take effect.
