[USN-6962-1] LibreOffice vulnerability
==========================================================================
Ubuntu Security Notice USN-6962-1
August 15, 2024
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:

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

CVE-2024-39292, CVE-2024-39471, CVE-2022-48674)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 20.04 LTS
linux-image-5.4.0-1135-azure 5.4.0-1135.142
linux-image-azure-lts-20.04 5.4.0.1135.129
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
