Scientific Linux Security Update : kernel on SL6.x i386/x86_64 (20130610)
high Nessus Plugin ID 66884
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
This update fixes the following security issues :- A flaw was found in the way KVM (Kernel-based Virtual Machine) initialized a guest's registered pv_eoi (paravirtualized end-of-interrupt) indication flag when entering the guest. An unprivileged guest user could potentially use this flaw to crash the host.
(CVE-2013-1935, Important)
- A missing sanity check was found in the kvm_set_memory_region() function in KVM, allowing a user-space process to register memory regions pointing to the kernel address space. A local, unprivileged user could use this flaw to escalate their privileges.
(CVE-2013-1943, Important)
- A double free flaw was found in the Linux kernel's Virtual Ethernet Tunnel driver (veth). A remote attacker could possibly use this flaw to crash a target system.
(CVE-2013-2017, Moderate)
The system must be rebooted for this update to take effect.
