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