Bug Fix Advisory - RHBA-2008:0189-5
------------------------------------------------------------------------------
Summary:
libvirt bug fix update

Updated libvirt packages that fix various bugs are now available.


Description:
Libvirt is a C toolkit to interact with the virtualization capabilities of
recent versions of Linux, and other operating systems.

These updated packages fix the following bugs:

* the xend_parse_sexp_desc() function used a fixed sized 4k buffer, which
could have been overgrown if the domain description was very complex. For
example, running the "virt-install" command with a large set of network
definitions, may have caused the XML description to exceed the 4k buffer.
When the buffer is re-allocated, libvirt tries to free the old buffer
address, resulting in a segmentation fault. As well, another buffer-growth
problem in libvirt has been resolved.

* a potential crash when applications use libvirt has been resolved.

Users of libvirt are advised to upgrade to these updated packages, which
resolve these issues.
