Type: security
Affected Mageia releases: 7
CVE: CVE-2020-24661

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)
