Summary
Red Hat Security Advisory: vdsm security, bug fix, and enhancement update

Notes

Topic
Updated vdsm packages that fix one security issue, various bugs, and add two enhancements are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Details
The Virtual Desktop Server Manager (VDSM) is a management module that serves as a Red Hat Enterprise Virtualization Manager (RHEV-M) agent on Red Hat Enterprise Virtualization Hypervisor (RHEV-H) or Red Hat Enterprise Linux hosts. VDSM allows RHEV-M to manage virtual machines and storage pools, and retrieve statistics from both hosts and guests. A flaw was found in the way VDSM handled the removal of a virtual machine's (VM) data back end (such as an image or a volume). When removing an image or a volume, it was not securely deleted from its corresponding data domain as expected. A guest user in a new, raw VM, created in a data domain that has had VMs deleted from it, could use this flaw to read limited data from those deleted VMs, potentially disclosing sensitive information. (CVE-2010-2223) These updated vdsm packages also fix the following bugs: * Kernel Samepage Merging (KSM) did not use all the available memory (due to the memory not being zero-filled) if the memory did not belong to the Linux guest. Thus, KSM was not effective in distributing the memory to the Linux guests with the result of shared memory being unavailable for Linux guests. With this update, KSM allows multiple Linux guests to share the memory. (BZ#527405) * the vds_bootstrap script failed when the host's temporary directory was located on a different partition, with the following error: [Errno 18] Invalid cross-device link using os.rename With this update, vds_bootstrap no longer fails. (BZ#530322) * vds_bootstrap failed to add a host to RHEV-M when the 'cpuspeed' and the 'libvirt' services were not found. With this update, the host is added to RHEV-M even when the aforementioned services are not present in the system. (BZ#538751) * previously, vds_bootstrap attempted to parse blank lines present in network scripts (for example, /etc/sysconfig/network-scripts/ifcfg-eth0). As a consequence, if a network script contained blank lines, vds_bootstrap failed and an error such as follows was written to /var/vdsm/vdsm.log (the error example below is consequent to the blank line being present in ifcfg-eth0): getBridgeParams: failed to read params of file /etc/sysconfig/network-scripts/ifcfg-eth0 Error:list index out of range With this update, vds_bootstrap filters blank lines in network configuration files, ensuring it does not fail if they are present. (BZ#540479) * the 'pool connect' utility did not save the master domain's information to the disk. If VDSM was restarted, auto-reconnect searched for a master domain with the highest version. If the master domain was not available at that time, an incorrect domain was chosen as the master. With this update, the correct domain is chosen as the master. (BZ#543432) * when using the RHEV-M interface to manage high-availability VMs, power down requests were not honored. Consequently, some high-availability virtual machines automatically rebooted instead of shutting down after they received a command to shut down. High-availability VMs now correctly process requests to shut down, with the result that no VMs incorrectly reboot instead. (BZ#547112) * after a host installation, the 'multipathd' service would restart when the host was started from a multipath device. With this update, the 'multipathd' service no longer restarts. (BZ#547305) These updated vdsm packages also add the following enhancements: * previously, import/export of VMs was not supported. With this update import/export have been implemented. (BZ#482608) * previously, the ISO image domain could not be shared with multiple Data Centers. The user had to define an independent ISO domain for each Data Center. With this update, the ISO image domain can be shared between multiple Data Centers. (BZ#496448) All vdsm users should upgrade to these updated packages, which resolve these issues and add these enhancements.
