- -------------------------------------------------------------------------

Package : libreoffice
Version : 1:6.1.5-3+deb10u10
CVE ID : CVE-2022-3874 CVE-2023-0950 CVE-2023-2255
Debian Bug :

LibreOffice an office productivity suite was affected by multiple


Libreoffice may be configured to add an empty
entry to the Java class path.
This may lead to run arbitrary Java code from the
current directory.


Improper Validation of Array Index vulnerability in the
spreadsheet component allows an attacker to craft a
spreadsheet document that will cause an array index
underflow when loaded. In the affected versions of LibreOffice
certain malformed spreadsheet formulas, such as AGGREGATE,
could be created with less parameters passed to the formula
interpreter than it expected, leading to an array index
underflow, in which case there is a risk that arbitrary
code could be executed.


Improper access control in editor components of
LibreOffice allowed an attacker to craft
a document that would cause external links to be loaded without prompt.
In the affected versions of LibreOffice documents
that used "floating frames"
linked to external files, would load the contents of those frames
without prompting the user for permission to do so.
This was inconsistent with the treatment of other linked
content in LibreOffice.

For Debian 10 buster, these problems have been fixed in version

We recommend that you upgrade your libreoffice packages.
