Summary
Red Hat Security Advisory: spice-vdagent-win security and bug fix update

Notes

Topic
An update for spice-vdagent-win that fixes one security issue and several bugs is now available. The Red Hat Security Response Team has rated this update as having important 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
spice-vdagent-win provides a service and an agent that can be installed and run on Windows guests. An unquoted search path flaw was found in the way the SPICE service was installed on Windows. Depending on the permissions of the directories in the unquoted search path, a local, unprivileged user could use this flaw to have a binary of their choosing executed with SYSTEM privileges. (CVE-2013-2152) This update also fixes the following bugs: * Previously, due to issues with some Windows guest applications, RHEV SPICE agent stopped getting clipboard changes. Now, the agent uses a new API that keeps track of clipboard changes, without the need to "trust" the behavior of other applications registered to the clipboard. (BZ#919451) * Previously, copying a .jpg or .png image file from specific applications, such as Mozilla Firefox, on a Windows guest, then pasting into a Linux client, resulted in an empty or black and white image due to incorrect pallete encoding in the guest vdagent. Now, the encoding has been fixed and copying and pasting works as expected. (BZ#919150) * Previously, when using a Windows virtual machine, enabling extra monitors with arbitrary configuration could fail. Now the agent enables the monitors before updating it to an arbitrary resolution to solve this issue. (BZ#922394) * Previously, if SPICE was disconnected in the middle of copying and pasting data from the client to the guest, copy and paste would stop working after SPICE was reconnected. Now, the clipboard timeout has been adjusted so that if SPICE is unexpectedly disconnected, the immediate copy and paste action will fail, but subsequent attempts will be successful. (BZ#833835) * Previously, when attempting to connect multiple displays using a Windows 7 guest, remote-viewer would only show one display available, even when all settings in the manager and on the SPICE client itself were correctly configured. This was caused by a regression issue relating to changes to custom resolution commands. Now, connecting and displaying multiple monitors functions correctly. (BZ#922283) * Previously, due to a regression caused by another patch, copying a .png image from specific applications, such as Firefox, on a Linux client, failed pasting into a Windows guest application, such as Paint, due to incorrect pallete encoding in the guest vdagent. Now, the encoding has been fixed and copying and pasting works as expected. (BZ#921980) * Previously, when a second user logged into a Windows guest, the RHEV SPICE Agent service terminated the previous vdagent instance, but mistakenly also the newly created vdagent on the current active session. Now, the vdagent termination event is reset after previous agent termination, so each new agent is no longer terminated. (BZ#868254) * Previously, if "RHEV SPICE agent" was stopped after copying data from a Windows guest, the client was not correctly notified, and assumed it could still paste the data. Now, agent termination has been fixed so that the client is notified to release the clipboard. (BZ#903379)
