When parsing the RBD hosts, it increments the 'nhosts' counter before increasing the 'hosts' array allocation. If an OOM then occurs when increasing the array allocation, the cleanup block will attempt to access beyond the end of the array. Switch to using VIR_EXPAND_N instead of VIR_REALLOC_N to protect against this mistake Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
