Package : qpdf
Version : 8.4.0-2+deb10u1
CVE ID : CVE-2018-18020 CVE-2021-25786 CVE-2021-36978

Several issues have been found in qpdf, a package with tools for
transforming and inspecting PDF files.
Crafted files may enable remote attackers to execute arbitrary code or
create recursive calls for a long time, which causes a denial of service.
Further a heap-based buffer overflow might occur when a certain downstream
write fails.

For Debian 10 buster, these problems have been fixed in version
8.4.0-2+deb10u1.

We recommend that you upgrade your qpdf packages.
