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

Medium Nessus Plugin ID 61313


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


This update fixes the following security issues :

- A flaw was found in the way the Linux kernel's journal_unmap_buffer() function handled buffer head states. On systems that have an ext4 file system with a journal mounted, a local, unprivileged user could use this flaw to cause a denial of service. (CVE-2011-4086, Moderate)

- A flaw was found in the way the KVM_CREATE_IRQCHIP ioctl was handled. Calling this ioctl when at least one virtual CPU (VCPU) already existed could lead to a NULL pointer dereference later when the VCPU is scheduled to run. A local, unprivileged user on a KVM host could use this flaw to crash the host. (CVE-2012-1601, Moderate)

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


Update the affected packages.
