Description Cathy Hu 2022-07-26 08:55:38 UTC
CVE-2022-26305

An Improper Certificate Validation vulnerability in LibreOffice existed where
determining if a macro was signed by a trusted author was done by only matching
the serial number and issuer string of the used certificate with that of a
trusted certificate. This is not sufficient to verify that the macro was
actually signed with the certificate. An adversary could therefore create an
arbitrary certificate with a serial number and an issuer string identical to a
trusted certificate which LibreOffice would present as belonging to the trusted
author, potentially leading to the user to execute arbitrary code contained in
macros improperly trusted. This issue affects: The Document Foundation
LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions prior to 7.3.1.
