.
* Team upload by LTS security team.
* Fix CVE-2023-6185: An Improper Input Validation vulnerability
was found in GStreamer integration of The Document
Foundation LibreOffice allows an attacker to execute arbitrary
GStreamer plugins. In affected versions the filename of the
embedded video is not sufficiently escaped when passed to
GStreamer enabling an attacker to run arbitrary
gstreamer plugins depending on what plugins are installed
on the target system.
* Fix CVE-2023-6186: LibreOffice supports hyperlinks.
In addition to the typical common protocols such as
http/https hyperlinks can also have target URLs that
can launch built-in macros or dispatch built-in
internal commands. In affected version of LibreOffice
there are scenarios where these can be executed without warning
if the user activates such hyperlinks. In later versions
the users's explicit macro execution permissions
for the document are now consulted if these non-typical
hyperlinks can be executed. The possibility to use these
variants of hyperlink targets for floating frames has been removed.
* Fix CVE-2020-12802: LibreOffice has a 'stealth mode' in which only
documents from locations deemed 'trusted' are allowed to
retrieve remote resources. This mode is not the default mode,
but can be enabled by users who want to disable LibreOffice's ability
to include remote resources within a document. A flaw existed
where remote graphic links loaded from docx documents were omitted
from this protection.
* Fix CVE-2020-12801: If LibreOffice has an encrypted document
open and crashes, that document is auto-saved encrypted.
On restart, LibreOffice offers to restore the document
and prompts for the password to decrypt it. If the recovery
is successful, and if the file format of the recovered document
was not LibreOffice's default ODF file format, then affected versions
of LibreOffice default that subsequent saves of the document
are unencrypted. This may lead to a user accidentally saving
a MSOffice file format document unencrypted while believing
it to be encrypted.
* Fix CVE-2020-12803: ODF documents can contain forms to be
filled out by the user. Similar to HTML forms, the contained
form data can be submitted to a URI, for example, to an external
web server. To create submittable forms, ODF implements the
XForms W3C standard, which allows data to be submitted without
the need for macros or other active scripting. LibreOffice allowed
forms to be submitted to any URI, including file: URIs, enabling
form submissions to overwrite local files. User-interaction
is required to submit the form, but to avoid the possibility
of malicious documents engineered to maximize the possibility of
inadvertent user submission this feature has now been limited to
http[s] URIs, removing the possibility to overwrite local files.
