RHBA-2012:0767 - Bug Fix Advisory

Topic

Updated spice-gtk packages that fix multiple bugs and add various enhancements
are now available for Red Hat Enterprise Linux 6.

Description

The spice-gtk packages provide a GTK2 widget for SPICE clients. Both
virt-manager and virt-viewer can make use of this widget to access virtual
machines using the SPICE protocol.

The spice-gtk packages have been updated to upstream version 0.11, which fixes
multiple bugs and adds multiple enhancements. These packages also add support
for native USB redirection. (BZ#773642)

This update also fixes the following bugs:

• 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.
(BZ#772118)

• 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. (BZ#805641)

• 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. (BZ#807389)

• 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.
(BZ#809145)

In addition, this update adds the following enhancement:

• Prior to this update, the spice-gtk widget did not provide a native USB

redirection. This update adds USB redirection support to spice-gtk. (BZ#758100)

All users of spice-gtk are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements.
