It was discovered that PDFResurrect was incorrectly validating header data in
input PDF files. An attacker could possibly use this issue to cause a heap
buffer overflow, resulting in a denial of service, or arbitrary code execution.
This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 ESM and Ubuntu 20.04 ESM.

Carter Yagemann discovered that PDFResurrect incorrectly handled certain memory
operations during PDF summary generation. An attacker could use this to
cause out-of-bounds writes, resulting in a denial of service (system crash)
or arbitrary code execution. This issue only affected Ubuntu 18.04 ESM and
Ubuntu 20.04 ESM. (CVE-2020-9549)

It was discovered that PDFResurrect was incorrectly processing data when
performing trailer search operations. An attacker could possibly use this issue
to cause an infinite loop, resulting in a denial of service. (CVE-2021-3508)");
