libreoffice vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

LibreOffice could be made to run programs if it opened a specially crafted
file.

Software Description:
- libreoffice: Office productivity suite

Details:

It was discovered that LibreOffice incorrectly allowed users to enable
macros when a cryptographic signature failed to validate. If a user were
tricked into opening a specially crafted document, a remote attacker could
possibly execute arbitrary macros.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
   libreoffice                     4:24.2.5-0ubuntu0.24.04.2

Ubuntu 22.04 LTS
   libreoffice                     1:7.3.7-0ubuntu0.22.04.6

Ubuntu 20.04 LTS
   libreoffice                     1:6.4.7-0ubuntu0.20.04.11

In general, a standard system update will make all the necessary changes.
