    Mageia 2020-0390: geary security update

    Date 21 Oct 2020

    Posted By LinuxSecurity Advisories
    GNOME Geary before 3.36.3 mishandles pinned TLS certificate verification for IMAP and SMTP services using invalid TLS certificates (e.g., self-signed certificates) when the client system is not configured to use a system-provided PKCS#11 store. This allows a meddler in the middle to present a different invalid certificate to intercept incoming and outgoing mail. (CVE-2020-24661)
