Detail

Synopsis

Multiple vulnerabilities have been found in libvirt, worst of which allows context-dependent attackers to escalate privileges.

Background

libvirt is a C toolkit for manipulating virtual machines.

Description

Multiple vulnerabilities have been discovered in libvirt. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker may be able to cause a Denial of Service or cause information leakage. A local attacker may be able to escalate privileges, cause a Denial of Service or possibly execute arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All libvirt users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-emulation/libvirt-1.2.9-r2"

Title: RHSA-2014:0560: libvirt security and bug fix update (Moderate)
Description: The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. It was found that libvirt passes the XML_PARSE_NOENT flag when parsing XML documents using the libxml2 library, in which case all XML entities in the parsed documents are expanded. A user able to force libvirtd to parse an XML document with an entity pointing to a special file that blocks on read access could use this flaw to cause libvirtd to hang indefinitely, resulting in a denial of service on the system. (CVE-2014-0179) Red Hat would like to thank the upstream Libvirt project for reporting this issue. Upstream acknowledges Daniel P. Berrange and Richard Jones as the original reporters. This update also fixes the following bugs: * When hot unplugging a virtual CPU (vCPU), libvirt kept a pointer to already freed memory if the vCPU was pinned to a host CPU. Consequently, when reading the CPU pinning information, libvirt terminated unexpectedly due to an attempt to access this memory. This update ensures that libvirt releases the pointer to the previously allocated memory when a vCPU is being hot unplugged, and it no longer crashes in this situation. (BZ#1091206) * Previously, libvirt passed an incorrect argument to the "tc" command when setting quality of service (QoS) on a network interface controller (NIC). As a consequence, QoS was applied only to IP traffic. With this update, libvirt constructs the "tc" command correctly so that QoS is applied to all traffic as expected. (BZ#1096806) * When using the sanlock daemon for managing access to shared storage, libvirt expected all QEMU domains to be registered with sanlock. However, if a QEMU domain was started prior to enabling sanlock, the domain was not registered with sanlock. Consequently, migration of a virtual machine (VM) from such a QEMU domain failed with a libvirt error. With this update, libvirt verifies whether a QEMU domain process is registered with sanlock before it starts working with the domain, ensuring that migration of virtual machines works as expected. (BZ#1097227) All libvirt users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically.

Description: The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. It was found that libvirt passes the XML_PARSE_NOENT flag when parsing XML documents using the libxml2 library, in which case all XML entities in the parsed documents are expanded. A user able to force libvirtd to parse an XML document with an entity pointing to a file could use this flaw to read the contents of that file; parsing an XML document with an entity pointing to a special file that blocks on read access could cause libvirtd to hang indefinitely, resulting in a denial of service on the system. (CVE-2014-0179) Red Hat would like to thank the upstream Libvirt project for reporting this issue. Upstream acknowledges Daniel P. Berrange and Richard Jones as the original reporters. This update also fixes the following bugs: * A previous update of the libvirt package introduced an error; a SIG_SETMASK argument was incorrectly replaced by a SIG_BLOCK argument after the poll() system call. Consequently, the SIGCHLD signal could be permanently blocked, which caused signal masks to not return to their original values and defunct processes to be generated. With this update, the original signal masks are restored and defunct processes are no longer generated. (BZ#1112689) * An attempt to start a domain that did not exist caused network filters to be locked for read-only access. As a consequence, when trying to gain read-write access, a deadlock occurred. This update applies a patch to fix this bug and an attempt to start a non-existent domain no longer causes a deadlock in the described scenario. (BZ#1112690) * Previously, the libvirtd daemon was binding only to addresses that were configured on certain network interfaces. When libvirtd started before the IPv4 addresses had been configured, libvirtd listened only on the IPv6 addresses. The daemon has been modified to not require an address to be configured when binding to a wildcard address, such as "0.0.0.0" or "::". As a result, libvirtd binds to both IPv4 and IPv6 addresses as expected. (BZ#1112692) Users of libvirt are advised to upgrade to these updated packages, which fix these bugs. After installing the updated packages, libvirtd will be restarted automatically.

Title: RHSA-2014:1873 -- libvirt security and bug fix update (Moderate)
Description: The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. An out-of-bounds read flaw was found in the way libvirt&#39;s qemuDomainGetBlockIoTune() function looked up the disk index in a non-persistent (live) disk configuration while a persistent disk configuration was being indexed. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to crash libvirtd or, potentially, leak memory from the libvirtd process. (CVE-2014-3633) A denial of service flaw was found in the way libvirt&#39;s virConnectListAllDomains() function computed the number of used domains. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to make any domain operations within libvirt unresponsive. (CVE-2014-3657) It was found that when the VIR_DOMAIN_XML_MIGRATABLE flag was used, the QEMU driver implementation of the virDomainGetXMLDesc() function could bypass the restrictions of the VIR_DOMAIN_XML_SECURE flag. A remote attacker able to establish a read-only connection to libvirtd could use this flaw to leak certain limited information from the domain XML data. (CVE-2014-7823) The CVE-2014-3633 issue was discovered by Luyao Huang of Red Hat. This update also fixes the following bug: When dumping migratable XML configuration of a domain, libvirt removes some automatically added devices for compatibility with older libvirt releases. If such XML is passed to libvirt as a domain XML that should be used during migration, libvirt checks this XML for compatibility with the internally stored configuration of the domain. However, prior to this update, these checks failed because of devices that were missing (the same devices libvirt removed). As a consequence, migration with user-supplied migratable XML failed. Since this feature is used by OpenStack, migrating QEMU/KVM domains with OpenStack always failed. With this update, before checking domain configurations for compatibility, libvirt transforms both user-supplied and internal configuration into a migratable form (automatically added devices are removed) and checks those instead. Thus, no matter whether the user-supplied configuration was generated as migratable or not, libvirt does not err about missing devices, and migration succeeds as expected. (BZ#1155564) All libvirt users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd will be restarted automatically.
