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…

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…

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…

An out-of-bounds buffer read flaw was found in the pluto daemon of libreswan from versions 3.27 till 3.31 where, an unauthenticated attacker could use this flaw to crash libreswan by sending specially-crafted IKEv1 Informational Exchange packets. The daemon respawns after the crash.
