The libguestfs packages contain a library, which is used for accessing and modifying virtual machine disk images. Security Fix: * 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. Note: The libguestfs packages in this advisory were rebuilt with a fixed version of OCaml to address this issue. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 6.9 Release Notes and Red Hat Enterprise Linux 6.9 Technical Notes linked from the References section.
