[oss-security] 20111024 kernel; CVE-2011-2942 and CVE-2011-3209

https://bugzilla.redhat.com/show_bug.cgi?id=730917

An updated rhev-hypervisor package that fixes several security issues is now available.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The rhev-hypervisor package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

The RHBA-2011:1254 update introduced a regression in the Linux kernel's Ethernet bridge implementation. If a system had an interface in a bridge, and an attacker on the local network could send packets to that interface, they could cause a denial of service on that system. (CVE-2011-2942)

A flaw in the Linux kernel could lead to GRO (Generic Receive Offload) fields being left in an inconsistent state. An attacker on the local network could use this flaw to trigger a denial of service. GRO is enabled by default in all network drivers that support it.
(CVE-2011-2723)

The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. (CVE-2011-3188)

Non-member VLAN (virtual LAN) packet handling for interfaces in promiscuous mode and also using the be2net driver could allow an attacker on the local network to cause a denial of service.
(CVE-2011-3347)

Red Hat would like to thank Brent Meshier for reporting CVE-2011-2723;
Dan Kaminsky for reporting CVE-2011-3188; and Somnath Kotur for reporting CVE-2011-3347.

This updated package provides updated components that include fixes for numerous security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however.

The security fixes included in this update address the following CVE numbers :

CVE-2011-2695, CVE-2011-2699, CVE-2011-3191, CVE-2011-1833, CVE-2011-2496, CVE-2011-3209, CVE-2011-2484, CVE-2011-3131, CVE-2009-4067, CVE-2011-1160, and CVE-2011-1585 (kernel issues)

Users of Red Hat Enterprise Virtualization Hypervisor should upgrade to this updated package, which resolves these issues.

From Red Hat Security Advisory 2011:1386 :

Updated kernel packages that fix multiple security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.
