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

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - A NULL pointer dereference flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could send a...

Scientific Linux Security Update : kvm on SL5.x x86_64

A flaw was found in the way QEMU-KVM handled the reloading of fs and gs segment registers when they had invalid selectors. A privileged host user with access to '/dev/kvm' could use this flaw to crash the host denial of service. CVE-2010-3698 The following procedure must be performed before this...

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

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A...

Scientific Linux Security Update : kernel on SL5.x i386/x86_64 (20120612)

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issues : - It was found that the Xen hypervisor implementation as shipped with Scientific Linux 5 did not properly restrict the syscall return addresses in the sysret...

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

Security fixes : - a missing capability check was found in the Linux kernel dochangetype routine. This could allow a local unprivileged user to gain privileged access or cause a denial of service. CVE-2008-2931, Important - a flaw was found in the Linux kernel Direct-IO implementation. This could...

Scientific Linux Security Update : xen on SL5.x i386/x86_64

Note: Troy Dawson has tested this update on a machine hosting both paravirtualized and fully virtualized machines, both 32 bit and 64 bit. He did the update while all the machines were running, none of them had any problems. He also tried stopping, starting, and rebooting several of the machines...

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

These updated packages fix the following security issues : - a flaw in the hypervisor for hosts running on Itanium architectures allowed an Intel VTi domain to read arbitrary physical memory from other Intel VTi domains, which could make information available to unauthorized users. CVE-2007-6207,...

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

This update fixes the following security issues : - A flaw was found in sctppacketconfig in the Linux kernel's Stream Control Transmission Protocol SCTP implementation.
