Hi Moritz,

Would appreicate if you can double check as well, my triage on those
issues: I looked at all three and further recent libpodofo issues and
the upstream "refactoring" in
https://github.com/podofo/podofo/commit/a2eca000e5a4337fb79ee8215d06413785653184
seems to be the cause. I then verified these three above with an ASAN
build of podofo.

If you think this is wrong, then let's revert
https://salsa.debian.org/security-tracker-team/security-tracker/-/commit/35925ae1ecb64f1cae0d3f456f0453532cfc6eaa
.

Regards,
