It was found that PDFtk, a tool for manipulating PDF documents, was vulnerable to an infinite loop if a crafted file was processed, which could result in denial of service.
For Debian 8 jessie, these problems have been fixed in version 2.02-2+deb8u1.
For Debian 9 stretch, these problems have been fixed in version 2.02-4+deb9u1.
We recommend that you upgrade your pdftk packages.
