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.

PROVIDED AND/OR DISCOVERED BY:
Reported by Richard W.M. Jones in a Red Hat bug report.
