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

High Nessus Plugin ID 77598

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.

Solution

Update the affected packages.
