- It was discovered that the spice-gtk setuid helper application, spice-client-glib-usb-acl-helper, did not clear the environment variables read by the libraries it uses. A local attacker could possibly use this flaw to escalate their privileges by setting specific environment variables before running the helper application.
- Prior to this update, the spice-gtk client could abort unexpectedly when the audio system failed to initialize. This update ignores audio initialization failures so that spice-gtk also works with failed audio system initialization.
- Prior to this update, memory leaks could, under certain circumstances, occur when the guest resolution was changed. This update modifies the underlying code so that changing the resolution no longer causes memory leaks.
- Prior to this update, videos showed a blue tint when using guests hosted on a Red Hat Enterprise Linux 5.8 host. This update uses the correct color conversion also on older SPICE servers so that videos are now correctly tinted.
- Prior to this update, copying large amounts of text could cause a stack overflow. As a consequence SPICE clients that use the spice-gtk widget could abort with a segmentation fault. This update no longer allocates large amounts of data on the stack and large clipboard data can now be copied to the server.
- Prior to this update, the spice-gtk widget did not provide a native USB redirection. This update adds USB redirection support to spice-gtk.
