Package: libpoppler147
Version: 25.03.0-5+deb13u2
Severity: normal

Dear Maintainer,

due to a small format problem in the "signing time" the generated signed PDF
cannot be verified as a fully correct QESig signature.

Upstream already fixed this with an one line patch:

https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/1824

Please consider to integrate patch, maybe even in next minor stable version.

Best regards,
Robert
