Last modified
CVE-2021-25635 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
