Scientific Linux Security Update : kvm on SL5.4 x86_64

CVE-2009-4031 kernel: KVM: x86 emulator: limit instructions to 15 bytes On x86 platforms, the doinsnfetch function did not limit the amount of instruction bytes fetched per instruction. Users in guest operating systems could leverage this flaw to cause large latencies on SMP hosts that could lead...

Scientific Linux Security Update : kvm on SL 5.4 x86_64

A flaw was found in the way QEMU-KVM handled erroneous data provided by the Linux virtio-net driver, used by guest operating systems. Due to a deficiency in the TSO TCP segment offloading implementation, a guest's virtio-net driver would transmit improper data to a certain QEMU-KVM process on the...

Scientific Linux Security Update : virt-v2v on SL6.x x86_64

virt-v2v is a tool for converting and importing virtual machines to libvirt-managed KVM Kernel-based Virtual Machine. Using virt-v2v to convert a guest that has a password-protected VNC console to a KVM guest removed that password protection from the converted guest: after conversion, a password...

Scientific Linux Security Update : kvm on SL5.4 i386/x86_64

The x86 emulator implementation was missing a check for the Current Privilege Level CPL and I/O Privilege Level IOPL. A user in a guest could leverage these flaws to cause a denial of service guest crash or possibly escalate their privileges within that guest. CVE-2010-0298, CVE-2010-0306 A flaw...

Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20120209)

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - Using the SGIO ioctl to issue SCSI requests to partitions or LVM volumes resulted in the requests being passed to the underlying block device. If a privileged...
