An Authentication Bypass vulnerability existed where the application bundled an interpreter (Python) that inherits the Transparency, Consent, and Control (TCC) permissions granted by the user to the main application bundle
By executing the bundled interpreter directly the attacker's scripts run with the application's TCC privileges
In fixed versions parent-constraints are used to allow only the main application to launch interpreter with those permissions

An Improper Certificate Validation vulnerability in LibreOffice allowed
an attacker to self sign an ODF document, with a signature untrusted by
the target, then modify it to change the signature algorithm to an
invalid (or unknown to LibreOffice) algorithm and LibreOffice would incorrectly present such a signature with an unknown algorithm as a
valid signature issued by a trusted person
This issue affects LibreOffice: from 7.0 before 7.0.5, from 7.1 before 7.1.1.

LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected versions of LibreOffice a link in a browser using that scheme could be constructed with an embedded inner URL that when passed to LibreOffice could call internal macros with arbitrary arguments.
This issue affects LibreOffice: from 24.8 before < 24.8.5, from 25.2 before < 25.2.1.

Certificate Validation user interface in LibreOffice allows potential vulnerability.
Signed macros are scripts that have been digitally signed by the
developer using a cryptographic signature. When a document with a signed
macro is opened a warning is displayed by LibreOffice before the macro
is executed.
Previously if verification failed the user could fail to understand the failure and choose to enable the macros anyway.
This issue affects LibreOffice: from 24.2 before 24.2.5.
