An integer overflow can occur while walking through tiles that could be exploited to corrupt memory and execute arbitrary code. In order to trigger this vulnerability, a victim would need to open a specially crafted XCF file. For Debian 9 stretch, these problems have been fixed in version 1.0.7-6+deb9u1. We recommend that you upgrade your xcftools packages.
