In VIPS, an image processing system, an uninitialized variable which may cause the leakage of remote server path or stack address was fixed.
For Debian 9 stretch, this problem has been fixed in version 8.4.5-1+deb9u2.
We recommend that you upgrade your vips packages.
For the detailed security status of vips please refer to its security tracker page at: https://security-tracker.debian.org/tracker/vips
