From secunia security advisory at $URL: Description A security issue has been reported in libguestfs, which can be exploited by malicious, local users to disclose potentially sensitive information. The security issue is caused due to the "virt-edit" utility not keeping original file permissions when editing a file inside a virtual machine image, which results in world-readable permissions being set. The security issue is reported in version 1.16.4. Other versions may also be affected. Solution Update to version 1.16.24.
All vulnerable versions were cleaned.
Thanks, fixed
