Oracle Linux Security Advisory ELSA-2011-2038 The following updated rpms for Oracle Linux 5 have been uploaded to the Unbreakable Linux Network: i386: kernel-uek-2.6.32-300.4.1.el5uek.i686.rpm kernel-uek-debug-2.6.32-300.4.1.el5uek.i686.rpm kernel-uek-debug-devel-2.6.32-300.4.1.el5uek.i686.rpm kernel-uek-headers-2.6.32-300.4.1.el5uek.i686.rpm kernel-uek-devel-2.6.32-300.4.1.el5uek.i686.rpm kernel-uek-doc-2.6.32-300.4.1.el5uek.noarch.rpm kernel-uek-firmware-2.6.32-300.4.1.el5uek.noarch.rpm ofa-2.6.32-300.4.1.el5uek-1.5.1-4.0.53.i686.rpm ofa-2.6.32-300.4.1.el5uekdebug-1.5.1-4.0.53.i686.rpm x86_64: kernel-uek-firmware-2.6.32-300.4.1.el5uek.noarch.rpm kernel-uek-doc-2.6.32-300.4.1.el5uek.noarch.rpm kernel-uek-2.6.32-300.4.1.el5uek.x86_64.rpm kernel-uek-headers-2.6.32-300.4.1.el5uek.x86_64.rpm kernel-uek-devel-2.6.32-300.4.1.el5uek.x86_64.rpm kernel-uek-debug-devel-2.6.32-300.4.1.el5uek.x86_64.rpm kernel-uek-debug-2.6.32-300.4.1.el5uek.x86_64.rpm ofa-2.6.32-300.4.1.el5uek-1.5.1-4.0.53.x86_64.rpm ofa-2.6.32-300.4.1.el5uekdebug-1.5.1-4.0.53.x86_64.rpm SRPMS: http://oss.oracle.com/ol5/SRPMS-updates/kernel-uek-2.6.32... http://oss.oracle.com/ol5/SRPMS-updates/ofa-2.6.32-300.4.... Users with Oracle Linux Premier Support can now use Ksplice to patch against this Security Advisory. We recommend that all users of Oracle Linux 5 install these updates. Users of Ksplice Uptrack can install these updates by running : # /usr/sbin/uptrack-upgrade -y On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf, these updates will be installed automatically and you do not need to take any additional action. Description of changes: * CVE-2011-4127: KVM privilege escalation through insufficient validation in SG_IO ioctl. Using the SG_IO IOCTL to issue SCSI requests to partitions or LVM volumes resulted in the requests being passed to the underlying block device. If a privileged user only had access to a single partition or LVM volume, they could use this flaw to bypass those restrictions and gain read and write access (and be able to issue other SCSI commands) to the entire block device. In KVM (Kernel-based Virtual Machine) environments using raw format virtio disks backed by a partition or LVM volume, a privileged guest user could bypass intended restrictions and issue read and write requests (and other SCSI commands) on the host, and possibly access the data of other guests that reside on the same underlying block device. (CVE-2011-4127, Important) * CVE-2011-1493: Insufficient validation in X.25 Rose parsing. Dan Rosenberg discovered that the X.25 Rose network stack did not correctly handle certain fields. If a system was running with Rose enabled, a remote attacker could send specially crafted traffic to gain root privileges. * Additional fix for CVE-2011-1576: Denial of service with VLAN packets and GRO. Oracle's previous fix for CVE-2011-1576 did not completely address the issue.
