Description
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.
Affected configurations
• libreoffice libreoffice (>= 7.0.0 < 7.0.5.1)
• libreoffice libreoffice (>= 7.1.0.0 <= 7.1.1.1)
