Summary
Although a fix for this was released in pdfminer version
20200726-1+deb11u2 (via DLA-4374-1), upstream subsequently determined
that this mitigation was insufficient and a more comprehensive
mitigation that replaces the pickle-based mechanism entirely was
applied instead.
For Debian 11 bullseye, this updated fix has been released in
version 20200726-1+deb11u2.
We recommend that you upgrade your pdfminer packages.
