"Virt-p2v is a tool for conversion of a physical server to a virtual
guest.

The following packages have been upgraded to a newer upstream version:
libguestfs (1.32.7), virt-p2v (1.32.7).

Security Fix(es) :

  - An integer conversion flaw was found in the way OCaml's
    String handled its length. Certain operations on an
    excessively long String could trigger a buffer overflow
    or result in an information leak. (CVE-2015-8869)

Note: The libguestfs packages in this advisory were rebuilt with a
fixed version of OCaml to address this issue.
