    Package        : libreoffice     Version        : 1:7.0.4-4+deb11u11     CVE ID         : CVE-2024-7788

    Various file formats are based on the zip file format. In cases of     corruption of the underlying zip's central directory,     LibreOffice offers a repair mode which will attempt to     recover the zip file structure by scanning for secondary local     file headers in the zip to reconstruct the document.

    Prior to this fix, in the case of digitally signed zip files,     an attacker could construct a document which, when repaired,     reported a signature status not valid for the recovered file.

    Previously if verification failed the user could choose     to ignore the failure and enable the macros anyway.

    Repair document mode has to be inherently tolerant,     so now in fixed versions all signatures are implied to     be invalid in recovery mode.

    For Debian 11 bullseye, this problem has been fixed in version     1:7.0.4-4+deb11u11.

    We recommend that you upgrade your libreoffice packages.
