Package : libreoffice
CVE ID : CVE-2021-25633 CVE-2021-25634

Two security issues have been discovered in LibreOffice's support for
digital signatures in ODF documents, which could result in incorrect
signature indicators/timestamps being presented.

For the stable distribution (bullseye), these problems have been fixed in
version 1:7.0.4-4+deb11u1.

We recommend that you upgrade your libreoffice packages.
