"Vulnerabilities have been discovered in pdfresurrect, a tool for
analyzing and manipulating revisions to PDF documents.

CVE-2019-14934

pdf_load_pages_kids in pdf.c doesn't validate a certain size value,
which leads to a malloc failure and out-of-bounds write

CVE-2020-20740

lack of header validation checks causes heap-buffer-overflow in
pdf_get_version()

For Debian 9 stretch, these problems have been fixed in version
0.12-6+deb9u1.

We recommend that you upgrade your pdfresurrect packages.
