Summary
Red Hat Security Advisory: rhev-hypervisor6 security and bug fix update

Notes

Topic
An updated rhev-hypervisor6 package that fixes several security issues and various bugs is now available. 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.
Details
The rhev-hypervisor6 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. A flaw was found in the way QEMU-KVM emulated the e1000 network interface card when the host was configured to accept jumbo network frames, and a guest using the e1000 emulated driver was not. A remote attacker could use this flaw to crash the guest or, potentially, execute arbitrary code with root privileges in the guest. (CVE-2012-6075) It was discovered that GnuTLS leaked timing information when decrypting TLS/SSL protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL server as a padding oracle. (CVE-2013-1619) It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169) A NULL pointer dereference flaw was found in the OCSP response verification in OpenSSL. A malicious OCSP server could use this flaw to crash applications performing OCSP verification by sending a specially-crafted response. (CVE-2013-0166) It was discovered that the TLS/SSL protocol could leak information about plain text when optional compression was used. An attacker able to control part of the plain text sent over an encrypted TLS/SSL connection could possibly use this flaw to recover other portions of the plain text. (CVE-2012-4929) This updated package provides updated components that include fixes for various 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-2013-0292 (dbus-glib issue) CVE-2013-0228, CVE-2013-0268, and CVE-2013-0871 (kernel issues) CVE-2013-0338 (libxml2 issue) This update contains the builds from the following errata: ovirt-node: RHBA-2013:0634 https://rhn.redhat.com/errata/RHBA-2013-0634.html kernel: RHSA-2013:0630 https://rhn.redhat.com/errata/RHSA-2013-0630.html dbus-glib: RHSA-2013:0568 https://rhn.redhat.com/errata/RHSA-2013-0568.html libcgroup: RHBA-2013:0560 https://rhn.redhat.com/errata/RHBA-2013-0560.html vdsm: RHBA-2013:0635 https://rhn.redhat.com/errata/RHBA-2013-0635.html selinux-policy: RHBA-2013:0618 https://rhn.redhat.com/errata/RHBA-2013-0618.html qemu-kvm-rhev: RHSA-2013:0610 https://rhn.redhat.com/errata/RHSA-2013-0610.html glusterfs: RHBA-2013:0620 https://rhn.redhat.com/errata/RHBA-2013-0620.html gnutls: RHSA-2013:0588 https://rhn.redhat.com/errata/RHSA-2013-0588.html ipmitool: RHBA-2013:0572 https://rhn.redhat.com/errata/RHBA-2013-0572.html libxml2: RHSA-2013:0581 https://rhn.redhat.com/errata/RHSA-2013-0581.html openldap: RHBA-2013:0598 https://rhn.redhat.com/errata/RHBA-2013-0598.html openssl: RHSA-2013:0587 https://rhn.redhat.com/errata/RHSA-2013-0587.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.
