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." } ] }, "generator": { "engine": "Vulnogram 0.0.9" }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-295 Improper Certificate Validation" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "url": "https://www.libreoffice.org/about-us/security/advisories/cve-2022-26305", "name": "https://www.libreoffice.org/about-us/security/advisories/cve-2022-26305" } ] }, "source": { "discovery": "EXTERNAL" } }
